[ovirt-users] Re: Permissions

[Staniforth, Paul]

Hello Boris,
 I think what you want is to set VmCreator either at the 
Datacenter or at Cluster level, also set DiskProfileUser at the Datacenter or 
Storage Domain if you want to limit them to creating disks in specific storage 
domains, if you set the VnicProfileUser on specific network profiles you can 
limit which networks they have access to.

Regards,
Paul S.

Hi
Does anybody have any solution that I want give some user or group permissions 
to create vm and fully manage only vm what he creates. So users should not be 
able to see or make any changes on vm what are not created by him/groups where 
user belong,

[ovirt-users] Re: Should I migrate existing oVirt Engine, or deploy new?

[Staniforth, Paul]

Hello David,
  I don't think there's a documentated method to go from a 
Hosted Engine to standalone just the other way standalone to HE.

I would suggest doing a full backup of the engine prepare the new VM and 
restore to that rather than trying to export it.
This way you can shut down the original engine and run the new engine VM to 
test it works as you will be able to restart the original engine if it doesn't 
work.

Regards,
Paul S.

Hello,
I have just purchased a Synology SA3400 which I plan to use for my oVirt 
storage domain(s) going forward. I'm currently using Gluster storage in a 
hyperconverged environment.

My goal now is to:

  *   Use the Synology Virtual Machine manager to host the oVirt Engine on the 
Synology
  *   Setup NFS storage on the Synology as the storage domain for all VMs in 
our environment
  *   Migrate all VM storage onto the new NFS domain
  *   Get rid of Gluster

My first step is to migrate the oVirt Engine off of Gluster storage / off the 
Hyperconverged hosts into the Synology Virtual Machine manager.

Is it possible to migrate the existing oVirt Engine (put the cluster into 
Global Maintenance Mode, shutdown oVirt, export to VDI or something, and then 
import into Synology's virtualization)? Or would it be better for me to install 
a completely new Engine, and then somehow migrate all of the VMs from the old 
engine into the new engine?

Thanks,
David

 Cannot update compatibility version of Vm/Template: [HostedEngine], Message: 
There was an attempt to change Hosted Engine VM values that are locked.

Also somehow the cluster had changed to Cluster Node Type of Virt only but

[ovirt-users] Re: remote-viewer VNC mode issue

[Staniforth, Paul]

Hi Patrick,

The ovirt-vmconsole is a for emulated serial connections (via a ssh tunnel).

The VNC ports are the same range as spice 5900 - 6923.

Do you have encryption enabled for VNC?

Hello,

Well a quick check of the hosts say that they have ovirt-vmconsole enabled on 
their firewall, but there doesn't seem to be any logs for the vmconsoles on 
them. Running wireshark on one of the end-user machines shows that the host 
does send packets back and forth but then the end-user machine TCP resets the 
connection. (I assume due to the credential failure.) So it doesn't seem to be 
a firewall issue.

Is there anything I can do to get some more logs from the vmconsoles on the 
Host?

Thanks.

[Staniforth, Paul]

Hi Sina,
 I get easily confused with cloud-init but shouldn't you be setting 
the hostname, username, etc before the custom script?

Also, you could rename the disk as a separate play in your playbook.

e.g.

# Change Disk Name
- ovirt.ovirt.ovirt_disk:
id: ----
storage_domain: data
name: "new_disk_name"
vm_name: rhel7

   Paul S.

Thanks Paul.

I seem to be getting this by hand, but trying with ansible, I think my skills 
are a bit lacking.
I can create with ansible, and it seems to work well, except for the fact that 
the new vm is
created with the hostname of the vm from which the template was made.
The disk is also named by the template.
My ansiblle yaml is below and I'm pretty sure its wrong (especially where it 
needs to use cloud-init to inject the correct hostname, and the other prepping 
I would like to add).
Please can you help correct me?

do not wish to do, because I would rather automate.

Cloning with ansible, defining the cloud-init script and using the template:
VM is successfully created, but logging in with remote-viewer drops me into the 
installation process (setting up from the attached ISO). Which is also not 
desired.

Please help me with what I am doing wrong.
Again the goal is to have the vm setup with its own credentials.

[ovirt-users] Re: How to debug "Non Operational" host

[Staniforth, Paul]

Hi Gervais,

  The engine doesn't need to be able to ping the IP address, just 
needs to know what it is so adding them to the /etc/hosts file should work.

Also, I would check ovirt1, is it mounting the brick, what does "systemctl 
status glusterd" show, what are the logs in /var/log/gluster ?

Hi Paul,

I don't quite get what you mean by this:

assuming you have a storage network for the gluster nodes the engine needs to 
resolve be able to resolve the host addresses

The storage network is on 10GB network cards and plugged into a stand-alone 
switch. The hosted-engine is not on the same network at all and can not ping 
the IP's associated with those cards. Are you saying that it needs access to 
that network, or that is needs to be able to resolve the IP's. I can add them 
to the /etc/hosts file on the ovirt-engine or do I need to reconfigure my 
setup? It was working as it currently configured before applying the update.

I have no idea why the ovirt1 server is not showing up with the fqdn. I set up 
all the servers the same way. It's been like that since I set things up. I have 
looked for where this might be corrected, but can't find it. Ideas?

The yellow bricks... I can force start them (and I have in the past), but now 
it turns green for a few minutes and then returns to red.

Cheers,
Gervais

the VMs disks is linked to the Templates disk and it just carries the changes

Caution External Mail: Do not click any links or open any attachments unless

Im sorry, I am trying to wrap my head around this but it is difficult.

I just want to be able to stand up new vms, with their own storage, similar to 
how I can with plain vanilla KVM, with a template or without, maybe even with a 
kickstart, and hopefully with ansible.

Right now anytime I try to create a VM, using the template, (with ansible), it 
gets the template disk attached, and from the console I see the new vm is named 
as the vm I created the template with. Cloud init script that is meant to 
rename the vm, and join it to IPA, is ignored.

If I create storage for the vm, before creating it, both the template storage 
and the new storage are attached to the vm, which is also confusing. Cloud init 
is also ignored.

I didn't think something this straightforward would end up needing a shift in 
thinking about how vms are created, especially with a product that's more than 
likely using kvm under the hood.

I would appreciate some straightforward guiding steps, if I can get them.
Really. It's been a frustrating week.

I'm not sure what minor version the system I restored it to.

Yes, I ran engine-setup after the restore.

I then did an upgrade to 4.4.9.4

I also upgraded the new system to centos8 stream.

Hi,

what is your version of runner and runner service?
rpm -qa "*ansible-runner*"
It is a bit strange that the /var/log/ovirt-engine/ansible-runner-service.log 
does not exist.

>From which version did you upgrade the engine?
Have you run the engine-setup after the restore?

Hi, can you please help me?
I deployed ovirt on an AWS instance, created a vm but during generation .vv the 
file, an private IP is put in the host field instead of an public one, which is 
why the remote-viewer does not connect to the vm. If I change the host from an 
private IP to an public one, then everything works. Where and how can I change 
this field ?

[ovirt-users] Re: Disconnected from Console. Cannot connect to websocket proxy server.

[Staniforth, Paul]

Hi,
   check the permissions and ownership of the certificate and key files, 
they are usually linked to apache.cer and apache.key.nopass.

you can check your configuration at

/etc/ovirt-engine/ovirt-websocket-proxy.conf.d/10-setup.conf

They should be owned by ovirt:ovirt

[ovirt-users] Re: Poor gluster performances over 10Gbps network

[Staniforth, Paul]

Hi Mathieu,
   with a linux VM using dd without the oflag=sync will 
mean it's using disk bufffers, hence the faster thoughput at the beginning 
until the buffers are full.

Hi Paul,

thank you for your answer.

Indeed I did a `dd` inside a VM to measure the Gluster disk performance. I've 
also tried `dd` on an hypervisor writing into one of the replicated gluster 
bricks, which gives good performances (similar to logical volume ones).

Hello everyone,

I know this issue was already treated on this mailing list. However none of the 
proposed solutions is satisfying me.

Here is my situation : I've got 3 hyperconverged gluster ovirt nodes, with 6 
network interfaces, bounded in bunches of 2 (management, VMs and gluster). The 
gluster network is on a dedicated bound where the 2 interfaces are directly 
connected to the 2 other ovirt nodes. Gluster is apparently using it :

Brick gluster-ov3:/gluster_bricks
/vmstore/vmstore

where 'gluster-ov{1,2,3}' are domain names referencing nodes in the gluster 
network. This networks has 10Gbps capabilities :

However, VMs stored on the vmstore gluster volume has poor write performances, 
oscillating between 100KBps and 30MBps. I almost always observe a write spike 
(180Mbps) at the beginning until around 500MB written, then it drastically 
falls at 10MBps, sometimes even less (100KBps). Hypervisors have 32 threads (2 
sockets, 8 cores per socket, 2 threads per core).

When I naively write directly on the logical volume, which is mounted on a

# dd if=/dev/zero of=a bs=4M count=2048
2048+0 records in
2048+0 records out
8589934592 bytes (8.6 GB, 8.0 GiB) copied, 17.2485 s, 498 MB/s #urandom gives 
around 200MBps

Moreover, hypervisors have SSD which have been configured as lvcache, but I'm 
unsure how to test it efficiently.

I can't find where is the problem, as every piece of the chain is apparently 
doing well ...

yes, it's not operating system version, but installed oVirt version on the
host (but not oVirt engine, there's only one engine and host haven't engine
installed).

Could you please improve the doc [1]?
Thanks

   The certificates are updated when you run engine-setup, you

Dear Listmembers,

How can I exctract the expiration dates all certificates which ovirt are uses?
Also, is there any command or tool in ovirt what I can use to create and deploy 
new certifications on hosted engine and hosts?

Thanks in advance,

Hi Paul,

We have had to maintain our own changes to the oVirt Vagrant plugin. Probably 
we need to start committing to and publishing our own fork.

Theres an obtuse and broken long one liner that get's the IP addresses, which 
has always been a bit problematic, and stopped working altogether with the 
newest release of oVirt we are using.

Anyway, here are the changes we made to get the IP addresses working with the 
new versions of oVirt:

line 58 wait_till_up.rb
  ip_addr = nil
  vm_nics_service = server.nics_service
  nics = vm_nics_service.list
  nics.each { |nic|
puts "Waiting on #{nic.mac.address}"

vm_nics_service.nic_service(nic.id).reported_devices_service.list.each { 
|device|
  device.ips&.each {|ip|
puts "ip: #{ip.to_s}"
if ip && ip.version == 'v4' && ip.address
  ip_addr = ip.address
  break
end
  }
}
  }

Also same in read_ssh.rb:
 ip_addr = nil
  vm_nics_service = server.nics_service
  nics = vm_nics_service.list
  nics.each { |nic|

vm_nics_service.nic_service(nic.id).reported_devices_service.list.each { 
|device|
  device.ips&.each {|ip|
if ip && ip.version == 'v4' && ip.address
  ip_addr = ip.address
  break
end
  }
}
  }
Sorry it's not the best way to share code, but feel free to pass this along.

Cheers,
Cliffe.

Anyone using vagrant with oVirt 4.4?

I am trying to get the vagrant plugin working with oVirt, but I am experiencing 
issues. 
https://github.com/myoung34/vagrant-ovirt4/issues/120<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fmyoung34%2Fvagrant-ovirt4%2Fissues%2F120=04%7C01%7Cp.staniforth%40leedsbeckett.ac.uk%7C2489f8033a8f4f960d4e08d8b0e08d88%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637453825790913752%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000=zfmBH3M%2BqyVRMPsoXPSSwMONjDS64Mz6nOpFdjiENkc%3D=0>
I wonder what other folks are using or if someone has any suggestions to offer.

We are trying to switch from vSphere to oVirt for internal, developer vm's at 
my office and we have a successful workflow using vagrant-vsphere plugin. 
Switching to oVirt should have been a simple step, but the issue I an having is 
a blocker.

I built a single hyperconverged server to test with. Everything seems to work 
fine when I bring up vm's manually in my "cluster." Networking, console, etc 
all work fine. Ovirt-guest-additions work fine and display the vm's ip in the 
gui.

When I try with the vagrant plugin, there seems to be a communication issue. 
Even though I can see the vm reporting its IP address fine in the ovirt web 
gui, it seems like the vagrant plugin is unable to do the same. The maintainer 
of the code says that he no longer runs oVirt which is why I am reaching out 
here to see if anyone has a suggestion or even an alternative to suggest.

Cheers,
Gervais

[ovirt-users] Re: How to cancel a longtime running task on ovirt web interface ?

[Staniforth, Paul]

Hello Tommy,
you can't cancel the task from the Web UI.

you can delete the job in the engine database

connect to the engine database

engine=#  select * from job;

to find the job_id  it will be the one without an end_time

select DeleteJob('job_id');


The other way  is to restart the oVirt engine.

Thanks,
 the gluster volume is just a test and the main reason was to test 
the upgrade of a node with gluster bricks.

I don't know why lvm doesn\t work which is what oVirt is using.

>1 node I wiped it clean and the other I left the 3 gluster brick drives 
>untouch.

If the last node from the original is untouched you can:
1. Go to the old host and use 'gluster volume remove-brick  replica 1 
wiped_host:/path/to-brick untouched_bricks_host:/path/to-brick force'
2. Remove the 2 nodes that you have kicked away:
gluster peer detach node2
gluster peer detach node3

3. Reinstall the wiped node and install gluster there
4. Create the filesystem on the brick:
mkfs.xfs -i size=512 /dev/mapper/brick_block_device
5. Mount the Gluster (you can copy the fstab entry from the working node and 
adapt it)
Here is an example:
/dev/data/data1 /gluster_bricks/data1 xfs 
inode64,noatime,nodiratime,inode64,nouuid,context="system_u:object_r:glusterd_brick_t:s0"
 0 0

6. Create the selinux label via 'semanage fcontext -a -t glusterd_brick_t 
"/gluster_bricks/data1(/.*)?"' (remove only the single quotes) and run 
'restorecon -RFvv /gluster_bricks/data1'
7. Mount the FS and create a dir inside the mount point
8. Extend the gluster volume:
'gluster volume add-brick  replica 2 
new_host:/gluster_bricks//

9. Run a full heal
gluster volume heal  full

10. Repeat again and remember to never wipe 2 nodes at a time :)


Good luck and take a look at Quick Start Guide - Gluster Docs

Assuming you don't care about data on the drive you may just need to use wipefs 
on the device i.e. wipefs -a /dev/sdb

Hi Kim,
   it will be using the engine hosts DNS configuration to find the

you can check with "dig _ldap._tcp.example.com SRV"

DNS and Active directory domains aren't the same thing.

there are examples of different A.D. configurations are in 
/usr/share/ovirt-engine-extension-aaa-ldap/examples

you can also use the tool  ovirt-engine-extension-aaa-ldap-setup

Some of the useful things to find out for you organization is
The forest name  A.D default domain, GC global catalogue.
as well as the UPN account the users probably have a sAMAccountName.

Subject: [ovirt-users] LDAP/AD issue

Caution External Mail: Do not click any links or open any attachments unless 
you trust the sender and know that the content is safe.

Hi all,

We have had our ovirt instance connected to our internal AD for users to log 
into the VM portal for the last year, linked to studentdomene.noroff.no. This 
has been working without any problems. We had it set up and the DNS server had 
a forward record to the DC's. All good.

Then, of course, the institution decided to introduce student emails and they 
decided to add the domain stud.noroff.no for student emails and made this the 
primary domain in the AD. The problem is that when this is changed, students 
can no longer log into the engine. I have of course changed the ldap settings 
and added a forward record on the DNS to the new domain. However, it seems that 
the domain is studentdomene.noroff.no, but with an added UPN suffix with 
stud.noroff.no

When students try to log in, with the config changes, they get this error in 
the browser:

server_error: An error occurred while attempting to query DNS in order to 
retrieve SRV records with name '_ldap._tcp.stud.noroff.no': 
NameNotFoundException(DNS name not found [response code 3]), 
ldapSDKVersion=4.0.7, revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58

Any ideas on how to solve this issue?

My config looks like this:

sudo cat /etc/ovirt-engine/aaa/Students.properties
[sudo] password for noroffadmin:
include = 

vars.domain = studentdomene.noroff.no
vars.user = CN=ovirt auth,CN=Users,DC=stud,DC=noroff,DC=no
vars.password = PASSWORD

pool.default.auth.simple.bindDN = ${global:vars.user}
pool.default.auth.simple.password = ${global:vars.password}
pool.default.serverset.type = srvrecord
pool.default.serverset.srvrecord.domain = ${global:vars.domain}

my forward on the DNS server looks like this:
sudo cat /etc/named/named.conf.local
[sudo] password for noroffadmin:
zone "platform.noroff.no"{
type master;
file "/etc/named/zones/db.platform.noroff.no";  # zone file path
};
zone "stud.noroff.no" {
type forward;
forward only;
forwarders { 172.24.111.20; 172.27.111.20; 172.21.111.20; 
172.16.111.20; };
};
zone "studentdomene.noroff.no" {
type forward;
forward only;
forwarders { 172.24.111.20; 172.27.111.20; 172.21.111.20; 
172.16.111.20; };
};
zone "122.16.172.in-addr.arpa" {
type master;
file "/etc/named/zones/db.122.16.172";  # 172.16.122.0/24 subnet
};

Any pointers would be greatly appreciated :)

[Staniforth, Paul]

Yes you could use affinity labels, can you remove hosts without breaking 
affinity? I had to set the affinity to soft/not enforcing when doing 
maintenance on hosts.

The only way to bulk add hosts is via the API/SDK.

The easiest would be ansible.

You might find affinity labels are a better fit in this use case. It would 
allow you to add/remove/move hosts in the future much more quickly than hard 
coding affinity. But that still leaves the bulk configuration tasks.

The only way to do this quickly is with the REST API or one of the SDKs that 
leverage it.

You'd create the affinity labels in the web UI then assign the VMs using the 
API.

Hi oVirt land

Hope you are well. Don't even know what to call this. But let me describe what 
I want to achieve.

We have a cluster with say 100 vm's. But we want two use two hosts in the 
cluster two run only certain VM's. I think you can do that with affinity rules. 
But how can I restrict those two hosts to only run the VM's, meaning that no 
other VM's will run on them.

I don't want to go and edit the 100 other VM's to not run on 2 hosts. Is there 
an easy way for doing this?

Oracle VM uses pools, I dont know what vmware uses.

Any advice will help.

Hi Ayansh,
as it's only changing the history database there isn't a 
high risk and you can run it while your system is being used,
For piece of mind you can do a full backup before, or just backup the Data 
Warehouse.

The credentials should be in

as your using 4.3 the version of postgresql is 10 and using scl

if it's using the standard user, database and is local.

years, is the Data Warehouse database local or remote? is there a firewall port 
open?

Can you connect to the database from the engine machine?

The credentials should be in 
/etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup-database.conf

as your using 4.3 the version of postgresql is 10 and using scl

scl enable rh-postgresql10 "psql  -h localhost -U  ovirt_engine_history  -d 
ovirt_engine_history"

if it's using the standard user, database and is local.


Regards,
Paul S.

[Staniforth, Paul]

Sorry Anton,
I'm trying to get a lot of things sorted before the 
weekend.

This seems the wrong way round, if you follow the documentation you shouldn't 
have the symbolic link on the working system unless you replaced the file it 
was pointing to.

Do you have certificate bundles for both systems?

Paul S.

Thanks Paul,



So the symbolic link has then been removed, as per the below. Not quite sure 
where to go from here.

Yes Anton,

 I think it's in the documentation it's



Steps 2 & 3

*

*  The Engine has been configured to use /etc/pki/ovirt-engine/apache-ca.pem, 
which is symbolically linked to /etc/pki/ovirt-engine/ca.pem. Remove the 
symbolic link.

 # rm /etc/pki/ovirt-engine/apache-ca.pem

*  Save your CA certificate as /etc/pki/ovirt-engine/apache-ca.pem.

 # cp /tmp/3rd-party-ca-cert.pem /etc/pki/ovirt-engine/apache-ca.pem

Hi Paul,



Double checked the permissions as well. All seems to be fine. The only thing 
that does look different between the environments are the below:



ENV1 (Not working)

[cid:image001.png@01D640B7.2B69DFC0]



ENV2 (Working)



[cid:image007.png@01D640B7.2B69DFC0]



It seems that on the working environment, there is a shortcut file 
(apached-ca.pem) which points to the ca.pem file, but on the environment that 
is not working, the apache-ca.pem file is not a shortcut. Could this perhaps be 
an issue?



Thanks

Hello Anton,

 if your organisation has it's own CA you can install your 
own certificates or get certificates from a trusted CA.

Hi Everybody,



With regards to noVNC, is it a requirement to install the CA into your local 
browser? I would like users to access their VM console, but with no additional 
work from their side, ie. Downloading the CA and importing it.



Thank you

Hello Anton,
 if your organisation has it's own CA you can install your 
own certificates or get certificates from a trusted CA.

Hi Everybody,



With regards to noVNC, is it a requirement to install the CA into your local 
browser? I would like users to access their VM console, but with no additional 
work from their side, ie. Downloading the CA and importing it.



Thank you

I found the time to work on this using the Python SDK.  Took me longer
than I wanted but I think I've got something working now.  I just
haven't done a FULL test, yet, but a runtime time on the online system
works (I commented out the start call).

I still have two files, a vm_list.py which is a config file that
contains the list of VMs, in order, and then the main program itself
(start_vms.py) which is based on several of the examples available in
github.

Unfortunately I can't seem to send the script in email because it's
getting blocked by the redhat server -- so I have no idea the best way
to share it.

[ovirt-users] Re: assign a specific user to a specific vm

[Staniforth, Paul]

When you look at the permissions tab for a VM you will see all the permissions 
and roles for users & groups, if it is an inherited permission it will show 
what object it is applied to e,g, database/cluster. You need to remove any that 
aren't appropriate.

I guess I need to clarify; when a user logs in to the vm portal, I only want 
them to see the machine assigned to them and have the ability to operate it.

How do I set the permission on a per user per vm basis to ensure the user has 
the same vm every time they login and that’s all they see is their vm.



That’s what I’m trying to accomplish.



Good example: In vmware, you can assign a specific user to a specific machine 
so that is there machine and that’s all they see.

[ovirt-users] Re: assign a specific user to a specific vm

[Staniforth, Paul]

Hello Eric,
  It sounds like you have permissions set to a group at some 
level, these are hierarchical  system->datacenter->cluster->VM

if you remove this permission and then set the userrole for the VM they should 
only be allowed to run this VM.

I'm not sure if I'm missing something or not, but I haven't seen how to assign 
a specific user to a specific vm. Is there a way to do that? When users login, 
they see all the machines. I'd like them to see just the one they need to login 
to.

Thanks in advance for your help.

[ovirt-users] Re: VM's in status unknown

[Staniforth, Paul]

I don't think the status is reported via the agent but vdsm on the host.

Try restarting the engine service.

use vdsm-client  on the host to see if the VM running and shut it down if 
needed.

https://www.ovirt.org/develop/developer-guide/vdsm/vdsm-client.html

on the host restart vdsmd ( you may want to migrate other VMs first)

systemctl restart vdsmd

If this doesn't work alter the database

Paul S.

I have Windows 10 and haven't experienced that. You can't shut it down in the

I will assume you have the latest guest tools installed.

Hi,

We have a few Windows 10 VM's running on our ovirt 4.3, where when you shutdown 
the VM from within Windows, that VM does not shut down but gets a status of 
unknown in ovirt and one cannot do anything to the machines within the web gui. 
This seems to specfically be related to that Windows 10 template that we have 
created. Any ideas? Also, any ideas on how one can shut these machines down?

Thanks

[ovirt-users] Re: Multiple NICs on hosted engine, oVirt 4.3

[Staniforth, Paul]

Sorry Jiri,
I don't have a self hosted engine add present so can't check 
which keys you can change but it says you can also append a configuration or 
answer file.
I think any changes should persist over updates, the local changes have to be 
applied to each node whereas the shared configuration is applied when a new 
host is deployed.

  Paul S.

Hello Paul,

thanks for reply and for pointing me to RHV documentation. Shame on me,
I forogot it exists and is well maintained and super relevant for oVirt.

But in this case I am a bit lost. I can't find something relevant to my
effort to modify HE vm's config to add the second NIC to it.

Or do you mean I should change the location of vm.conf from /var/run
location to something persistent and then modify this vm.conf as
mentioned in that old post?

For example, now I got this output for conf key

[root@ovirt-hci01 ~]# hosted-engine --get-shared-config conf
--type=he_shared

conf : /var/run/ovirt-hosted-engine-ha/vm.conf, type : he_shared

[root@ovirt-hci01 ~]# hosted-engine --get-shared-config conf --type=he_local

conf : /var/run/ovirt-hosted-engine-ha/vm.conf, type : he_local

Is it valid to change it to (for example)
/etc/ovirt-hosted-engine/vm.conf and modify that file there? Is it safe
for further updates, maintenance, etc.?

Maybe the second question - which process creates vm.conf in /var/run path?

Cheers,

Jiri

.Hello Tommaso,
   on your oVirt engine host run
check the north bridge controller
ovn-nbctl show
this should show a software switch for each ovn logical network witch any ports 
that are active( in your case you should have 2)

check the south bridge controller
ovn-sbctl show
this should show the software switch on each host with a geneve tunnel.

on each host run
ovs-vsctl show
this should show the virtual switch with a geneve tunnel to each other host and

  *   eth1, with 1922.168.1.1/24

VM B

the eth1 interfaces are connetter by a network created on external provider 
ovirt-network-ovn , whithout a subnet defined.

Now, the external ip works fine, but the two vm cannot connect through the

[ovirt-users] Re: bare-metal to self-hosted engine

[Staniforth, Paul]

Hello Kim,
   as it says in the documentation a SHE setup  is more complex 
to maintain, see the following about upgrades, configuration changes and 
backups.
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html/administration_guide/chap-administering_the_self-hosted_engine

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html/administration_guide/chap-backups_and_migration#Backing_up_and_Restoring_a_Self-hosted_Engine

Also there doesn't seem to be any documentation to move from back from SHE to a 
standalone engine.

Regards,
Paul S.

 and it seems OK.
Also,  you can take a look at 
https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Faccess.redhat.com%2Fdocumentation%2Fen-us%2Fred_hat_virtualization%2F4.3%2Fhtml-single%2Fmigrating_from_a_standalone_manager_to_a_self-hosted_engine%2Findexdata=02%7C01%7Cp.staniforth%40leedsbeckett.ac.uk%7Cb8c8f8c52d35493eaf1008d7d198d2e2%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637208326609022043sdata=WL4YLvQU4YKAyDN8VFeUqdKNU%2F6Lu2EvsZmSoR13ExU%3Dreserved=0

I would recommend you to:
A)  creare a backup of the engine
B) create a test setup (for example in VMs) to prepare yourself for the process.

Hello everyone,

is there a way to seperate the traffic between VMs on the same bridge on one 
oVirt-node with built-in tools from ovirt? We have VMs using the same bridge 
which should never be able to talk to each other.

We are currently using ebtables for that, but its not working very good anymore 
now that we upgraded to 4.3 with firewalld.

Any suggestions would be greatly appreciated.

Best regards,
Hendrik

Please assist as it currently seems the Quota permissions are not working as 
expected. The Quotas storage_inf1 and storage_dev2 are configured in exact same 
way, expect that they are for different DataCenters.

Hello Anton,
   you can also manually do this
edit 
/etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup-scale.conf
run  systemctl  restart  ovirt-engine-dwhd.service

if you upgrade your engine it puts the old  10-setup-scale.conf back but it 
keeps a copy

Hi Everybody,

I have a question. When oVirt was deployed in our environment by previous

to get the daily stats, as this is now empty due to the scale. Is this just as 
simple as described in the following article: 
https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt.org%2Fdocumentation%2Fdata-warehouse%2FChanging_the_Data_Warehouse_Sampling_Scale.htmldata=02%7C01%7Cp.staniforth%40leedsbeckett.ac.uk%7Cca53316d625742be286908d7c0414bb2%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C1%7C637189258999725533sdata=ywsasun9mV0sNSjCmEeIf%2B94UZdc%2Fc%2Bevx9A1ScodXQ%3Dreserved=0

Are there any precautions I should take, and has anybody else ever done this 
before?

Thanks a lot

Hi Eugène

can't you use ansible add-hoc commands ?


for a common cli to (libvirt, KubeVirt, oVirt, OpenStack, VMware vSphere, GCP 
and AWS) you could try kcli 
https://github.com/karmab/kcli/blob/master/doc/index.md ( although I haven't 
tried it yet).

Yes Ansible ovirt_vms module is useful, I use it for provisioning/deployment, 
but once my VM created, I'd like to administrate/interact with them, I don't 
think I should write playbooks for that.

But I'll find a solution.

Did you try one of the SDKs?

Also the ansible modules are useful for many cases.

install with the same credentials. If you delete the postgresql config you can 
then install with your postgres credentials.

e.g.
systemctl stop rh-postgresql10-postgresql.service
rm -rf /var/opt/rh/rh-postgresql10/lib/pgsql/data/*

I did get a little further.

First I ran engine-cleanup on my new engine where I will be running the restore 
operation. (I had previously run the engine-setup script on this machine)

Then I ran this-

[root@engine ~]# engine-backup --mode=restore 
--file=ovirt-engine-backup-20200217125040.backup 
--log=ovirt-engine-backup-20200217125040.log --provision-db --provision-dwh-db 
--restore-permissions

Restoring:

Provisioning PostgreSQL users/databases:

FATAL: Existing database 'engine' or user 'engine' found and temporary ones

Time to research further for that FATAL error message.  Isn't that the purpose 
of engine-cleanup though?  Why the conflict?

Try looking at the RHEV info here and go to section 6.2.2 and see if that helps.

OK, I was able to get the backup completed.  I am a little confused on how to 
do the restore though.  
https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environment.html

Is this link even applicable?  My environment is a single node, not EL based.  
Anyhow, here is what I have so far-

[root@engine glusterfs]# engine-backup
Start of engine-backup with mode 'backup'
scope: all
archive file: 
/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup

Packing into file 
'/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup'
Notifying engine
Done.
[root@engine glusterfs]#

I moved the backup file to my new engine.
How do I perform the restore?

The directions say:

# engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --provision-dwh-db --restore-permissions

What is the file name and log_file name?  Do I need to do something to unpack 
my backup file?

Subject: [ovirt-users] Huge increase of CPU load on hosted engine VM after 
upgrade to 4.3.8 and cluster compatibility version

Caution External Mail: Do not click any links or open any attachments unless

Hi,

I have upgraded yesterday one of our ovirt environments from 4.2.8 to 4.3.8.
We have a hosted engine, 25 hosts and about 150 VMs running there.

After upgrading the cluster compatibility version from 4.2 to 4.3, I have seen 
a huge increase of CPU load on the engine VM.
The engine had 4 cores (16GB mem) and never had load issues, but after the 
upgrade, the system has a load of 6 and more. I have increased the CPUs to 8, 
because working in the UI was impossible.

I have noticed, that the load always increase, when I load the VM UI tab, where 
now all VMs have the orange triangle with pending changes: Custom compatibility 
version

The problem I have, is, that I can't reboot now all VMs, maybe in the next 3 or 
4 weeks.
Working now with the UI is quite problematic, because of the slowness.

The engine VM was already rebooted, but didn't solve the problem.

What logs do you need and is there a workaround available? I have some more 
oVirt environments to upgrade, all with even more VMs.

BR Florian

Hi to all.

I'm try to create a glance server to store our images, but I have some problem.

With the guide i can correcty configure a "train" minimun stack with keyone and 
glance, but it only support auth api v3. oVirt for glance only support v2.

The newest version of keystone that have the v2 api, is Pike, but it cannot be 
insalled on centos today.

Where a can fine an old repo with pike packages? or how can i make a glance 
installation that doesn't require autentication?

Yes that's what usually happens the VM will be paused when the backing storage 
starts running out of space, try deleting the ISO from where you uploaded it to.

Got everything installed and was uploding an ISO when the system just stopped 
responding.  Went to the host and saw the hostedengine was paused.  Looked 
online and found the following instructions for unpausing it

virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf
resume HostedEngine

And get the following error
Failed to acquire lock: No space left on device

any ideas?

I have successfully imported the disk image into oVirt and attached to a new VM

When I power on, though, they all give me a "kmode exception not handled".

Hello Matt,
   probably the easiest setup to test/evaluate oVirt it to use 
ORB
https://www.ovirt.org/documentation/ovirt-orb/
oVirt Orb | oVirt
oVirt is a free open-source virtualization solution for your entire enterprise
www.ovirt.org
>From version 4.2 you can setup a single node hyper-converged install but it

https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Introduction.html
Introduction | 
oVirt
Chapter: Introduction. Hyperconvergence is a type of infrastructure system with 
a software-centric architecture that tightly integrates compute, storage, 
networking and virtualization resources and other technologies from scratch in 
a commodity hardware box supported by a single vendor[1].

You could also use nested virtualization on KVM and virt-manager, use your host 
to provide NFS, iscsi or gluster and then provide a nested VM for the engine 
and hosts.

That was my original configuration, but I found that it wouldn't let me add the 
local machine as a host, and so I thought perhaps I needed to use the 
self-hosted deployment methodology instead.

Would a regular engine be better for my deployment type? If so, I can 
investigate why that isn't working, and start over.

[Staniforth, Paul]

Hi Jingjie,
   It sounds like you are using linux hosts try yum 
check-update and yum update. The ovirt-node-ng-image-update is for when you 
have installed oVirt Node, you can't change from an enterprise linux host to a 
node without deleting the host and reinstalling using the oVirt node iso as it 
installs to a bare-metal system.

https://www.ovirt.org/documentation/install-guide/chap-Introduction_to_Hosts.html
Introduction to Hosts | 
oVirt<https://www.ovirt.org/documentation/install-guide/chap-Introduction_to_Hosts.html>
Host Type Other Names Description; oVirt Node: Thin host: This is a minimal 
operating system based on Enterprise Linux. It is distributed as an ISO file 
and contains only the packages required for the machine to act as a host.

Hi Paul,

Thanks for your reply.

I did install ovirt-release43 before I install the ovirt-node-ng-image-update 
package.


Here is the brief procedure:

1. Install the 4.2.8 ovirt host on CentOS7.6 by adding the node from 
AdminPortal.

2. Upgrade ovirt 4.2.8 engine to 4.3.6.

3. Set the host to maintainence from AdminPortal.

4. Yum install ovirt-release43 rpm

# yum install 
http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm<https://eur02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fresources.ovirt.org%2Fpub%2Fyum-repo%2Fovirt-release43.rpm=02%7C01%7CP.Staniforth%40leedsbeckett.ac.uk%7C0d525d532c154c58539e08d799e7fb77%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637147093957065741=uq2mpS1NASO%2BnSzePccVJRm4m8DxgunPDZZelqf3Y6E%3D=0>

5.Yum install node update package

   # yum install 
https://resources.ovirt.org/pub/ovirt-4.3/rpm/el7/noarch/ovirt-node-ng-image-update-4.3.6-1.el7.noarch.rpm<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fresources.ovirt.org%2Fpub%2Fovirt-4.3%2Frpm%2Fel7%2Fnoarch%2Fovirt-node-ng-image-update-4.3.6-1.el7.noarch.rpm=02%7C01%7CP.Staniforth%40leedsbeckett.ac.uk%7C0d525d532c154c58539e08d799e7fb77%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637147093957075730=rvoaa06KnxYN18Caz9Sn7CuEwOwcKuJHCw6%2BBaPbLoY%3D=0>

6. reboot


vdsm did not get update.

 Jingjie,
   I think you need to install 
https://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fresources.ovirt.org%2Fpub%2Fyum-repo%2Fovirt-release43.rpm=02%7C01%7CP.Staniforth%40leedsbeckett.ac.uk%7C0d525d532c154c58539e08d799e7fb77%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637147093957085722=QTYjvkIEg%2FZTnXSeatNEDEtxXVnYR2r4qdPk77i9%2FZA%3D=0>
 so yum updates to the 4.3 release otherwise it will stay on the 4.2 release 
(4.2.8 being the last version).

Hi Jingjie,

  If you have a node installed using ovirt-node-ng it created a 
thin LVM pool and ovirt-node-ng-image-update creates a new LVM layer so you 
have 2 versions of the node that you can switch between.

Thanks Dominik,
  That pointed me in the correct direction, the 
ovn-controller.log was full of

stream_ssl|WARN|SSL_connect: unexpected SSL connection close

on the engine  ovn-sbctl  get-ssl produced no output

so after a hint from ovn-nbctl  get-sslI ran

ovn-sbctl set-ssl  /etc/pki/ovirt-engine/keys/ovn-sdb.key.nopass 
/etc/pki/ovirt-engine/certs/ovn-sdb.cer /etc/pki/ovirt-engine/ca.pem

and everything is working again 

From the logs it appears that this happened around 3:30am last Friday but I 
can't think why?

Hello I was testing the ovirt-provider-ovn which was working but at some point

Sounds like the ovn-controller on the hosts has a problem.

Please ensure that the ovn-controller is running on all relevant hosts.
If it is running and not working, can you please share the ovn-controller.log 
with us?

Do you have any idea, what happened to the point in time it stopped working?
I heard similar stories already multiple times, but in the past, the users just 
restarted ovn-controller and all hosts and it was working again,
but it would be helpful to understand why it was stopped, to prevent this from 
happening again.



The logical networks are created and VMs have their ports created and attached 
on the hosts they run or migrate to but their are no geneve tunnels created and 
on the engine host "ovn-sbctl show" produces no output.
Any help appreciated.

Thanks,

Hi,
if you have a network in the cluster that is set to required any hosts 
in the cluster will become non-operational if it's isn't available. You can set 
the logical network not to be required while testing or if it isn't essential.

Caution External Mail: Do not click any links or open any attachments unless 
you trust the sender and know that the content is safe.

I do use  automatic migration policy.

The main question you have to solve is:
1. Why the nodes became 'Non-operational' .Usually this happens when the 
management interface (in your case HoatedEngine VM) could not reach the nodes 
over the management network.

By default, management is going over the ovirtmgmt network. I guess you have 
created the new network. Marked that new network as management network and then 
the switch was off , causing 'Non-Operational  state'.

2. Migrating VMs is usually a safe approach, but this behavior is quite 
strange. If a node ia Non-operational ->  there could be no successful 
migration.

3. Some of the VMs got paused  due to storage issue.  Are you using GlusterFS, 
NFS or iSCSI ? If yes, you need to clarify why you lost your storage.

I guess  for now you can mark each VM to be migrated only manually (VM -> Edit) 
and if they are critical VMs , set a high Availability from each VM's Edit 
options.

In such case, if a node fails, the VMs will be restarted on another node.

4.  Have you setup node fencing ? For example APC, iLo, iDRAC and other fencing 
mechanisms can allow the HostedEngine use another Host as fencing proxy and to 
reset the problematic Hypervisor.

P.S.: You can define the following alias  in '~/.bashrc' :
alias virsh='virsh -c 
qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf'
Then you can verify your VMs even when a HostedEngine is down:
'virsh list --all'

migration, and only a few virtual machines are pulled up again due to cancelled 
migration

After I tried to terminate the migration tasks and restart ovirt-engine  
service, I was still unable to restore most of the virtual machines, so I had 
to restart 3 ovirt-nodes to restore my virtual machine

I didn't recover all the virtual machines until an hour later


Then  I modify my migration policy  to " Do Not Migrate Virtual Machines"

Which migration Policy do you recommend?

I'm afraid to use cluster...

[ovirt-users] Re: ovirt vdsm and networking

[Staniforth, Paul]

Hi Kim,

   you should be able to from the admin portal for the interfaces 
of your hosts go into setup host networks and change the boot protocol for your 
student network to manual or dhcp.

If you don't want your student VMs having network access to your hosts you 
could configure a separate display network or setup a spice and websocket proxy.

Subject: [ovirt-users] ovirt vdsm and networking

Hi,

We are running CentOS and ovirt 4.3.4. We currently have four nodes and have 
set up the networks as follows:

ovirtmanagmeent network - set up as a tagged vlan with a static IP
SAN network - set up as a tagged vlan with a static IP
student network - set up as a tagged vlan
fw network - set up as a tagged vlan

The ovirtmanagement and SAN networks were configured on the CentOS boxes during 
after installing CentOS and before adding the nodes as hosts. The student 
network and the fw network were configured through the ovirt admin panel. 
However, because of this, the student network is not assigned a static IP on 
the nodes and serves the VM's using the DHCP on the firewall. The ovirt 
management network is set as the display network and every time I try to change 
that to the student network, ovirt admin panel tells me that I can't because 
there is no IP address assigned to the student network vlan. I tried using ip 
addr add to add a static IP on the one CentOS node, but this does not get 
picked up by ovirt and of course ovirt controls the actual vlan files on the 
CentOS box through VDSM, so any changes I make there will likely just be 
overwritten.

So, my question is, should I stop VDSM, add the IP to the vlan files on the 
CentOS nodes and then restart VDSM or is there a proper way of solving this? I 
need the Display Network to be set to the student network.

Thank you for any help.

[Staniforth, Paul]

Hello Matthias,

The oVirt hosts need to be registered in redhat satellite as a content host and 
the satellite host will need to have the centos and oVirt yum repositories 
added so they can create a content view. The first step I would do is ask 
whoever manages your satellite server if they are managing any Centos hosts.

[ovirt-users] Re: Clusters: Clarification needed on the ballooning memory feature and its affects on the physical hosts memory

[Staniforth, Paul]

Hello Donagh,
 memory size  e.g. 62000MB is the memory the VM tells 
the O/S is available you should be able to see how much is actually used if the 
agent is installed.
  maximum memory e.g. 248000MB is the amount you can 
hot-plug for the VM otherwise you need to restart the VM to increase memory.
  physical memory guaranteed e.g. 31000MB is the amount 
of memory the VM will have even if the balloon driver is activated.

The VMs will use memory as required, you can see how much memory they are 
actually using, also how much shared memory are the hosts using and how much is 
available to schedule new VMs?

Subject: [ovirt-users] Clusters: Clarification needed on the ballooning memory 
feature and its affects on the physical hosts memory

Hi

For test purposes I'm configuring cluster with ballooning enabled and memory 
over-commit set to 200% with one host (total memory 128600 MB) connected. I 
then create 4 linux based VM's and I set the following on each: memory size: 
62000MB, max memory: 248000MB (default value set when memory size is set) and a 
guaranteed memory value of 31000MB (default value set when memory size is set).

This all works as expected, I can start 4 VM's with a total memory size that 
double the physical memory available on the host. What I don't understand is 
when I view the general info on my host I see that the available memory is much 
higher than expected. Physical Memory:128600 MB total, 11574 MB used, 117026 MB 
free.

When researching the set up required to test this feature I came across this 
post 
https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.ovirt.org%2Fpipermail%2Fusers%2F2017-October%2F084675.htmldata=02%7C01%7Cp.staniforth%40leedsbeckett.ac.uk%7C3f6fe3e41c434eaa268808d77d58b65e%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637115692286198137sdata=x3r%2Bwz%2FM8CvwE7JIk5LBypnKMjxIwY8oDvDTdB8wM4c%3Dreserved=0.
 It states the hosts memory load needs to exceed 80%. I was hoping that the 
allocation of physical memory to each VM would satisfy this condition but I am 
not sure it does. I have a few questions on this

Should setting the physical memory to each VM would satisfy the greater than 
80% conditions?
Given we have guaranteed memory for each VM of 31000MB should the total of 
124000Mb exceed the free memory on the host?
Does the hosts used physical memory only represent each VM's disk 4Gb virtual 
size?
Will the hosts free memory only decrease as the VM's consume storage?

Any clarification on the above questions would be most appreciated.

Donagh

as the error suggests Windows 8 onward defaults to not

You should probably disable fast-boot on the Windows guest.

[Staniforth, Paul]

Hello Dirk,
The link you are using is old developer docs, try the following.
https://www.ovirt.org/documentation/admin-guide/chap-External_Providers.html

You need to setup an external provider and use a proxy host in the datacentre 
(not the engine host) you want to import into, this needs to be on the same 
network as your KVM host and have the virt-v2v package installed.

https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt.org%2Fdevelop%2Frelease-management%2Ffeatures%2Fvirt%2FKvmToOvirt.htmldata=02%7C01%7Cp.staniforth%40leedsbeckett.ac.uk%7C44f2fc1e1e5644fbc17008d7797444c4%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637111412591121899sdata=L0oVqmTjUoaYQlpmIN8AK9JjNvq8ZVVMP0LQusnbsuU%3Dreserved=0

After that, i take a look on the official 4.3 Rhev Documentation from Red Hat. 
There stand this:

Log in to the proxy host and generate SSH keys for the vdsm user.

sudo -u vdsm ssh-keygen

So, i have no proxy host.  So i want to do this on my ovirt-engine. Is this 
right?

Next thing: the user vdsm is locked on the ovirt-engine machine and the host.

So, do i have to unlocked the account of the user vdsm or what is the best way.

My Problem is i found nothing that would help me to solve this problem.

Maybe somebody here do me a favour and help me to solve this "challenge"

Regards

Dirk

[ovirt-users] Re: restore

[Staniforth, Paul]

As you did a full backup including the data warehouse you need

engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --provision-dwh-db --restore-permissions

see

Hi,

I did a backup of engine like this

In a newly installed machine try to restore it:

# yum update
# yum install ovirt-engine
# engine-backup --mode=restore --file=file_name --log=log_file_name

It prevents only the packager component.

If you already have 4.3.6 installed, which was the original question,
then engine-setup will still update the database schema. And if it
didn't, the 4.3.6 engine might fail working correctly with a 3.4.5.5
database. In particular:

The documentation for engine-backup always stated that you must run
engine-setup immediately after restore. But at some points in time,
and under certain conditions, this was actually optional. You could
have done a restore, and immediately start the engine, and it would
have worked. But this isn't the case if your restored db is older than
the installed engine. Then, you must run engine-setup before starting
the engine.

In principle it should be ok. After you restore with above command,
you should run 'engine-setup', and this will update your restored
database schema to 4.3.6.
This is not routinely tested explicitly, though, but I expect that
people often do this, perhaps even unknowingly, when they restore from
a backup taken with a somewhat-old version.

In theory you can change last one to 'yum install
ovirt-engine-4.3.5.5'. I didn't try that, and you are quite likely to
run into complex dependencies you'll have to satisfy by yourself.

I think the best solution for you, if you care about active and
standby to be identical, is to upgrade your active one as well, and
keep them same version going forward.

I'd also like to note that maintaining a standby engine and using it
the way you intend to, is not in the scope of oVirt. People do similar
things, but have to manually work around this and be careful. One very
important issue is that if for any reason you allow both of them to be
up at the same time, and manage the same hosts, they will not know
about each other, and you'll see lots of confusion and errors.

You might also want to check:

1. Hosted-engine setup with more than one host as hosted-engine host.
There, you only have a single engine vm, but it can run on any of your
hosts. You still have a single VM disk/image, and 

[ovirt-users] Re: Quick question regarding FQDN

[Staniforth, Paul]

Hello Christian,
  That recommendation is for the hyper-converged 
installation as the nodes are also the storage servers so you would choose the 
storage addresses when setting up the gluster network.
The other thing is you may have to setup a display network proxy if your 
clients can't reach nodes.

Subject: [ovirt-users] Quick question regarding FQDN

Hey folks,

for production use quality it is recommended to have backend (storage)
and front end seperated. Let' assume:

  - 85.0.0.0/24 public IP block
  - 10.100.0.0/24 private IPs for DC internal usage
  - 10.200.0.0/24 private IPs for storage only LAN

and running, as per recommendation 3 nodes:

  - node01:
- fqdn: node01.dc-example.com
- fqdn storage: node02.storage.example.com
- no public IP
- 10.100.0.1 primary IP
- 10.200.0.1 storage IP

  - node02:
- fqdn: node02.dc-example.com
- fqdn storage: node02.storage.example.com
- no public IP
- 10.100.0.2 primary IP
- 10.200.0.2 storage IP

  - node03:
- fqdn: node03.dc-example.com
- fqdn storage: node02.storage.example.com
- no public IP
- 10.100.0.3 primary IP
- 10.200.0.3 storage IP

The storage network is its own physical network with 10gig that only
connects those three servers. How can I specify which IP to use for
storage, which for frontend traffic?

I am assuming this as the controller and all admins should be able to
reach the nodes via frontend, which is not the storage one.

Okay, I am lost. Whats the real solution here?
Or is "frontend" no-ip, just VM traffic and "backend" is the 10gig
storage "Only" where all the FQDN reside?

Thanks for clarification,
-Chris.

[ovirt-users] Re: Quick generic Questions

[Staniforth, Paul]

Hello Christian,

here are some useful links

https://www.ovirt.org/documentation/gluster-hyperconverged/Gluster_Hyperconverged_Guide.html


https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.6/

You need to have at least 1 device for the O/S node install and at least 1 
device for the bricks, so ideally mirror 2 for the O/S and raid the rest + 
spare.

a) Yes the the oVirt node installer has a hyperconverged/gluster mode.

b) The storage will be shared between all 3 nodes and distributed to bricks on 
all 3 nodes.

c) The VM can start and migrate on / to all nodes if all requirements are met 
(mem/cpu/networks) as the storage is shared.

d) I don't think so

e) storage network should not die VMs will probably be paused and if nodes lose 
access to storage on the master storage domain I think theengine will 
restart them depending on fencing policy.
The gluster network should be a separate from the front-end network and use 
bonds for resilience.

f) yes you can add more shared storage domains using ISCSI, FC, NFS external 
gluster storage with ISCSI it may be better to use multipath connections rather 
than a bond.

Paul S.

Subject: [ovirt-users] Quick generic Questions

Hey folks,

I am looking at setting up a hyperconverged cluster with 3 nodes (and
oVirt 4.3). Before setting up I have some generic questions that I would
love to get hints or even an answer on.

First off, the Servers are outfittet with 24 (SSD) drives each in a
HW-RAID. Due to wear-leveling and speed I am looking at RAID10. So I
would end up with one giant sda device.

a) Partitioning
Using oVirt node installer which will use the full size of /dev/sda is
this still the right solution to Hyperconverged given the gluster issue?
If I understood it correctly gluster is using empty drives or partitions
so a fully utilized drive is of no use here. Does oVirt node installer
have a hyperconverged/ gluster mode?

b) Storage Location
In this 3 node cluster, creating a VM on node01 will the data for node01
always end up in the local node01 server?

c) Starting VMs
Can a VM be migrated or launched from node03 if the data resides on
node01 and node02 (copies 2 with arbiter).

d) Efficiency / High IO Load
If node01 has high IO Load would additional data be loaded from the
other node which has the copy to even the load? I am aware Virtuozzo
does this.

e) Storage Network dies
What would happen with node01, node02 and node03 are operational but
only the storage network dies (frontend is still alive as are the nodes).

f) external isci/ FreeNAS
We have a FreeNAS system with tons of space and fast network
connectivity. Can oVirt handle storage import like remote iscsi target
and run VMs on the ovirt nodes but store data there?

Thank you for your time to clear this up.
I have found many approaches out there that either are old (oVirt 3) or
even contradict themselves (talk about RAID level...)

Cheers!
-Christian.

Subject: [ovirt-users] Move Hosted Engine to external oVirt or VMware

Hi,

I've got a oVirt Infrastructure with 4 nodes and a self-hosted engine. The 
hosted engine also manages additional 4 nodes in 4 datacenters.

Two tasks:
- Re installation of our infrastructure without interfering or interrupting the 
external nodes.
- Separate the external hosts from our infrastructure by either leaving them in 
the old hosted engine or setting up a new hosted engine on VMware or the new 
Ovirt Infrastructure

We've already drained 2 of our 4 nodes, re-installed them with ovirt node and a 
new self-hosted engine and moved our VMs onto it.
On the two remaining nodes only runs the old self-hosted engine which still 
manages the 4 external hosts - which prevents me from reinstalling that 
remaining hosts. I'd prefer to move the old HE to the new oVirt Installation or 
to our VMware infrastructure. Is that possible and what pitfalls do I have to 
care of?

Many thanks for any hint on this!
Markus

[ovirt-users] Re: Trying to add a LUN to a host and use that, instead of Gluster, as the datastore for my VM's.

[Staniforth, Paul]

I think you should be able create a gluster volume from the local LUN on each 
server and use these to create 2 storage domains.

They should then be shared storage but not replicated so if a host goes down 
you will loose that domain.

Maybe you will need to alter the fencing policy?

  Paul S.

 Allright.

 So I followed this and configured local storage.  It had some default
 names that I changed.  It would have been either the default name, or
 one I choose.  In either case it would be a different name then the
 Gluster storage domain the host was a part of anyway.

 Once the process completed for both hosts, I noticed the Gluster
 volume storage domain was offline and the gluster volume was gone.  I
 can't seem to add that back in anymore.  I get:

 "Error while executing action DisconnectStorageServerConnection: Error
 storage server disconnection"

 Guessing I can't have local storage in addition to Gluster on the same
 hosts and available for VM's?

 Reason why I need that is that Gluster is slow but provides redundancy
 and live migration.  But I also wanted direct storage for VM's
 requiring faster IO.  So here's my scenario:

 host01
 /dev/sda OS
 /dev/sdb 4TB (For Gluster)
 /dev/sdc 4TB (For Local Storage)

 host02
 /dev/sda OS
 /dev/sdb 4TB (For Gluster)
 /dev/sdc 4TB (For Local Storage)

 I would like to have:

 1) GlusterFS volume available to oVirt via the two /dev/sdb drives in
 both physical hosts.
 2) Two locally attached LUN's, each separate and local to that
 physical host.

 Is this possible?

Hi Kim,


If you add them to a group in AD then add the users and group to oVirt you can 
add the permissions to the group.

Then add the VmCreator and DiskProfileUser to the Datacenter.
Add the UserTemplateBasedVM  permission to any templates you want them to be 
able to use

Add the VnicProfileUser permission to any vNIC profiles they should have access 
( make sure public isn't enabled on any vNIC profiles you don't want them to 
have access to)

When they create a VM they will then get UserVmManager permission and the 
DiskOperator permissions on any disks.

This means they should be able to do all 1 to 8 for their own VMs and also 
delete their VMs and Disks.

At least in 4.1.9, oVirt re-scans the ISO domain for new files, so you
should be able to scp your .iso file directly into the domain and have it
appear in the engine after some re-scan period.  I.e., at least
historically there was no hard-and-fast requirement to upload an ISO image
through an ovirt interface.

That may have changed in 4.2 and/or 4.3, but I hope not.

[ovirt-users] oVirt 4.3 gluster hooks

Hello,

   In an oVirt 4.3 cluster there are a number of gluster hooks out of

with operation cancelled with the error message "Error while executing action

In the engine log there are a number of errors  including

Subject: [ovirt-users] Custum driver in oVirt node image?

Using 3 Mini-ITX Atoms J5005 boards to build a three node HC test environment 
(actually there is a fourth to simulate a remote DC)

These boards have a RealTek 8169 Gbit controller, which for hardware/firmware 
or driver reasons comes up just fine on cold boots, but struggles on warm-boots 
or whenever the interface is re-configured, as is the case when the OVS overlay 
is configured, ...

* unless link-speed autonegotiation is enabled

after which it works just fine.

So for a normal system, I can just put a proper ETHTOOL_OPTS="autoneg on" into 
/etc/sysconfig/network-scrkipts/ifcfg- to avoid trouble on warm 
boots, but once the overlay network is put on top, the network manager no 
longer controls the device and the standard "ignore" setting of driver/hardware 
evidently causes the link to fail: dmesg reports the interface toggling and ovs 
isn't happy either.

The Ethernet switch is unmanaged, so there is nothing I can do there to speed 
up or eliminate negotiations, and I currently see three options:
1. Find/be told where to renable Ethernet link speed autonegotiation with the 
OVS/VDSM/?? so the RTL8169 is happy again
2. Use a known USB3 GBit NIC (no space in the chassis to put e.g. an Intel NIC)
3. Make an USB3 2.5Gbit NIC based on RealTek's 8156 work, but currently that 
requires compiling from source and loading it at boot

Option 3 works just fine with a CentOS base, but I got tons of problem making 
oVirt hosted engine work with that.
Option 3 for the oVirt node image seems to class with the read-only nature of 
the oVirt node imge: While I can load a pre-compile driver interactively, I 
can't make it stick with dracut -f.

I haven't immediately found a way to patch/fix/build derivative oVirt node 
images with that driver included and am somewhat to impatient to wait until 
it's mainstream, so any help would be appreciated.

I've verified option 2 with a single USB3 GBit adapter natively supported by 
the kernel that I already had available, but I then opted to jump the gun and 
buy the slightly more expensive 2.5GBit variant as a better match to a Gluster 
environment: A mistake in this context as it turned out.

Hello,

  there also seems to be a lot of queries send to the engine database, 
this is the problem I had with 70 VMs in compatibility  mode as this really 
slowed the admin portal down while querying running VM's  for instance.

Hello Sharon,

I had a look on the bug report and it says, that this fix is targeted for oVirt 
4.4. This would be really bad for us, because I have hundreds of VMs, which 
can't be restarted so easily (over 500) and this would break then our engine...
This would make it impossible for us to upgrade to oVirt 4.3.5 or higher until 
the Bug is fixed.

Would it be possible to get a manual fix for this?

I would like to upgrade to 4.3.6 when it is out in September or beginning of 
October.

Betreff: [ovirt-users] Re: engine.log flooded with "Field 'foo' can not be

Hi,
We checked that issue and found out that you are right and this extra logging 
lines problem is caused by "next run configuration" improvements added to oVirt 
4.3.5.

The current behaviour is that for each running VM with next run configuration 
existed, a warning line of "Field 'xxx' can not be updated when status is 
'Up'" appears in log, per each vm device and whenever the vms list is refreshed.
This definitely may flood the engine log if there are few such VMs.

Can you please file a bug on that?

Thanks,
Sharon

I still hope it's linked to unfinished VM "Custom Compatibility Version"

My "Administration Portal" is still usable, but nevertheless I think
this is something the upstream developers should look into.

[ovirt-users] Re: Need to enable STP on ovirt bridges

[Staniforth, Paul]

I haven't used FC with oVirt but in the following it shows the bridge options 
available and how to enable Ethtool and FCoE.

Subject: [ovirt-users] Need to enable STP on ovirt bridges

Hello. I have been trying to figure out an issue for a very long time.
That issue relates to the ethernet and 10gb fc links that I have on my
cluster being disabled any time a migration occurs.

I believe this is because I need to have STP turned on in order to
participate with the switch. However, there does not seem to be any
way to tell oVirt to stop turning it off! Very frustrating.

After entering a cronjob that enables stp on all bridges every 1
minute, the migration issue disappears

Is there any way at all to do without this cronjob and set STP to be
ON without having to resort to such a silly solution?

Here are some details about my systems, if you need it.


selinux is disabled.

[ovirt-users] Re: Evaluate oVirt to remove VMware

[Staniforth, Paul]

Hello Allen,
  In oVirt you can use VLANs and Bonds but not teaming. It may 
be useful to try a Centos(oVirt uses Centos or RHEL) install to see how the 
networking works, most notably you add devices that are VLANs or BONDs. I also 
check that the devices are enables on boot as I have been caught out with this 
which is especially annoying when doing remote installs.

The power management uses other hosts as a proxy so you need at least 2 in a 
cluster but you can configure this later.


Regards,
Paul S.

Subject: [ovirt-users] Evaluate oVirt to remove VMware

Howdy All!!!

Somewhat new user to Linux and having some issues with oVirt node networking.
We are mainly a Windows/VMware medium shop but have a pretty good network.

Our VMware setup has redundant switches using multiple VLANs. This was fairly 
easy to setup with VMware.
We never had an issue with VMware, add 2 NICs to the ESXi host and then adding 
VLANs into the Virtual Switch.

Biggest issue I am having, should I be bonding, teaming and VLANing on top of 
that?
Tried setting up node with Engine inside which fails to deploy because of 
networking.

Then I tried a standalone Engine and could not add node to it - I believe 
networking as well as Power Management agent was the problem.
Would like the nodes/engine to be on one subnet (lets say 10.10.11.x) and VMs 
to be allowed to run there are well as 10 other VLANs.

I guess welcome to the wonderful world of Linux networking and learning some 
new technologies is in store for me.
I hope I am not being vague, like I said fairly new to Linux.

Thanks for any responses!
Allen

It shouldn't, since has no use in the engine node - other than
silencing those errors.

Which OVS / OVN version are you using ?

[ovirt-users] Re: Need to enable STP on ovirt bridges

[Staniforth, Paul]

Maybe try changing it in /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt

I'm not networking expert but isn't the migration network just for traffic when 
transferring the VM between hosts. I think the problem is more because your VM 
network connection is transferred to a new host and port on your physical 
switch.

Paul S.

Hi Paul,

Thank you very much for the response. However, I have tried those
options. Adding "stp=on" does not enable STP on the bridges. Each node
has a 1Gb Ethernet connection as well as a 10Gb FC connection, I've
tried moving the VM migration network to each and the effect is the
same.

The vdsm disables STP when it writes the ifcfg-em0 or ifcfg-p1p1 files
in /etc/sysconfig/networking-scripts.

This behavior can been seen when using the standard "brctl show"
utilities directly logged into the host. Can the templates that the
VDSM uses to write those files be modified, possibly?

Thank you!
