It is perfect, It creates new disk, uses the configuration of CPU and also
assigns separate memory.

Thanks, both of you.

If it's working as expected, and you only ask us "how?", then you might
want to check openuds docs. Perhaps it logs you in with different users?
No idea. What OS is running on the VM?

When you check oVirt's admin console, do you see only one VM? Where are
VDI_1 and VDI_2 defined, and how? Did you define the vm by yourself, or
used openuds to do that for you?

You might want to change the subject of your email to something like
'oVirt and openuds'.

You can add the host to ovirt, converting the hosts to ovit host.

There is no way to external host.

Hi,

Are you using the rpm from the nightly builds.
Please add this line to your inventory file

openshift_logging_es_nodeselector={'node-role.kubernetes.io/infra':

I believe it will solve this error.

Hi Marcelo,

I'm sorry you are having issues with the installation, we are working to 
improve that.

I wanted to update you that I have update the OpenShift version to install to 
3.11 instead of 3.9,
so that it will fit to the OpenShift latest version and this should simplify 
the support for the installation by the OpenShift team.
It is available in the latest oVirt nightly and documentation is up to date
https://ovirt.org/documentation/metrics-install-guide/metrics-install-guide/

Also, I want to let you know that in the next release we plan to add support 
for an all-in-one installation that will create the vm/s for you and install 
OpenShift on them.
This should simplify immensely the process of setting up the oVirt metrics 
store.

I'll contact the OpenShift team for help about your issue as well, But you may 
want to install version 3.11 instead.
Please let me know if decide you want to try installing the latest version.

Best regards,

[ovirt-users] Re: Replicated storage gets erased when added to new environment.

[Christopher Cox]

Don't think so.  AFAIK, but this might have changed in 4.x.  But usually 
to float "stuff" between datacenters, you have to export to an export 
domain and then do an import.


1. Attach non-attached export domain
2. Export VMs (must include templates if from templates)
3. Detach export domain.
4. On new datacenter, attach export domain
5. Import VMs
6. Detach export domain.

There might be come sort of unsupported way to take a Storage Domain 
into a different datacenter, I'm just not aware of such.  Thus, the idea 
of a "replicate" would have to be a full "replicate" in a failover style 
scenario where you can't really tell the difference between the two (the 
storage domain works on the replicate because it can't tell the 
difference).  Thus, only one could ever be "up" at any time.  Even so, I 
haven't tried to do this.  If the metadata contains something so 
intrinsic to the the hypervisor cluster that it can't be effectively 
replicated, obviously this isn't going to work without some sort of 
assist that can massage/convert the metadata.


IMHO (again, I'm not up on any 4.x stuff that might have made this 
easier/possible)

So I am assuming in a real disaster recovery scenario the Ansible stuff 
is doing some magic there.


However, I would like to know if I properly detach a Fiber Channel 
storage domain, is it simple to import it to a new environment. Any 
guidance before I undertake such a task?

"Import Domain" So I was able to import the replicated iSCSI domain, 
however now when I try to attach the storage domain, I get the 
following in the even log.

It is my opinion that my problem now is that since the data domain was 
not properly detached before replication, that my replicated storage 
will not attach because of some "lock" on the storage domain?Is that 
what this error means or am I missing the mark completely?

Normally a "replicate" or RAID 1 style scenario is handled by a SAN

So, the answer lies with your storage supplier and/or SAN abstractor.

With that said, reading your full text, this would still be likely 
for a failover scenario and not a "live/live" scenario. A "live/live" 
scenarios risks the problem inherent to two things being "split 
brained".  And this is usually very bad for non-cluster aware storage 
(and the complexity of cluster aware storage could be great in this 
case).

[ovirt-users] Re: Replicated storage gets erased when added to new environment.

[Jacob Green]

Ok I found my answer in the *engine.log *"Domain 
'80dcf277-9958-4368-b7dd-2a5d5d29b3ec' is already attached to a 
different storage pool, clean the storage domain metadata."


So I am assuming in a real disaster recovery scenario the Ansible stuff 
is doing some magic there.


However, I would like to know if I properly detach a Fiber Channel 
storage domain, is it simple to import it to a new environment. Any 
guidance before I undertake such a task?

It is my opinion that my problem now is that since the data domain was

will not attach because of some "lock" on the storage domain?Is that 
what this error means or am I missing the mark completely?

So, the answer lies with your storage supplier and/or SAN abstractor.

With that said, reading your full text, this would still be likely 
for a failover scenario and not a "live/live" scenario. A "live/live" 
scenarios risks the problem inherent to two things being "split

[ovirt-users] Networking - interface and security questions

[davidk]

Hello,

I'm trying to setup a new ovirt install and have run into some general issues 
that I hope someone can help with.

I'm somewhat new to ovirt (but not virtualization).

First off, I've been doing lots of reading and I can't seem to find what the 
generally accepted method is for firewalling access between networks and VMs is 
in ovirt?  I see references to network filters, but no obvious ways to set 
ports or modify the configuration beyond a set list of general good-practice 
policies (no arp spoofing, etc).

What do people use in a production environment?  Trunk out to an external 
firewall and do the filtering there?  Run iptables or some rules locally in 
each VM? Or just run pfSense or other firewall software as another VM and 
manage it there?

And lastly, I'm trying to setup a new interface using the external ovn provider 
but am having problems.

I can define the external provider network just fine (not connected to physical 
network), but can't seem to actually use it.

When I create a new VM and assign the new network to an associated interface, 
the VM fails to start.

The error I get is: 

"VM testvm is down with error. Exit message: Cannot get interface MTU on 
'br-int': No such device."

Am I missing something obvious here?

I'm running oVirt 4.2.7 with the latest oVirt Node on a few hosts (also 4.2.7).

All my configuration has been via the web interface so far.

Sincerely,
___

[ovirt-users] Re: LDAP Bind failing because of SSLHandshakeException after Virtualization Manager was rebooted

[Will Hegedus]

So, it turns out that one of the domain controllers had a different certificate 
chain (outside of my team's control) which was inexplicably causing the whole 
thing to fail.

I would run "ovirt-engine-extensions-tool --log-level=FINEST 
--log-file=/tmp/aaa.log aaa login-user --user-name=prea...@liberty.edu 
--profile=liberty.edu" and everything would look fine up until the point that 
it needed to "doFetchPrincipalRecord", at which point it would fail to get the 
principal record for the account. The bind would succeed, but because "Creating 
LDAPConnectionPool" would fail on *just one* of the domain controllers, it for 
some reason seemed to invalidate all of the entries in that pool, thereby 
causing the fetching of principal records to fail even though the bind 
succeeded on one of the OK domain controllers.

Is this behavior intended? I really think this should be classified as a bug.

For what it's worth, this was resolved by getting the certificate chain from 
the problem DC and then adding it to the Java Keystore with the other 
certificate chain that all the other domain controllers use.

Normally a "replicate" or RAID 1 style scenario is handled by a SAN

[ovirt-users] LDAP Bind failing because of SSLHandshakeException after Virtualization Manager was rebooted

[wbhegedus]

After moving and rebooting our Red Hat Virtualization Manager box to another 
node in our cluster, we are unable to make LDAP login work using StartTLS. No 
networking or configuration changes were made, but the logs indicate that the 
TLS negotiation is failing with our Active Directory domain controllers now. 
Specifically: 

"2018-11-13 10:33:12,500-05 WARN  
[org.ovirt.engineextensions.aaa.ldap.Framework] (ServerService Thread Pool -- 
49) [] Exception: The connection reader was unable to successfully complete TLS 
negotiation:  SSLHandshakeException(sun.security.validator.ValidatorException: 
No trusted certificate found), ldapSDKVersion=4.0.5, 
revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58"

I have tried everything I can think of. I removed and reimported the 
certificate for the domain controller in the Java Keystore. I deleted the 
profile entirely and recreated it. I tried using the full certificate chain and 
I tried using single certificates from the chain, and all combinations together.

For now, we have it working by specifying "pool.default.ssl.insecure = true" in 
the .properties file, but I'd prefer to have this working again using StartTLS. 
Is there something I am missing? I want to make sure that I'm not overlooking 
something before submitting any sort of bug report.

Any help is appreciated. Thanks!

PS - this is what the properties file looks like:
[root@rhvm ~]# cat /etc/ovirt-engine/aaa/liberty.edu.properties 
include = 

vars.domain = liberty.edu
vars.user = cn=PREADER,ou=Service

vars.password =

[ovirt-users] How to force a QoS IO limit update to all disks

[Florian Schmid]

Hi,

oVirt version: 4.2.5.1

I have a strange problem with IO limiting.
I have a storage domain for our dev environment and I have set the default Disk 
Profile to a QoS rule with IO limit enabled.
This rule is working so far, but when I change the QoS rule of this default 
Disk Profile to a different IO limit, all the disks have still the old limit 
active.

Only when I edit the disk and click OK without changing anything, I see also in 
Events, that the new IO limit is set.
This behavior would cause me a lot of work, because we have several 100s of 
disks and I can't edit all, only to have new QoS active.

Is there another way to do this bulk change of disk IO limit?

What data do you need to have a look on?

EDIT:
I saw now, that the QoS policy is automated updated on some VMs and there only 
on some disks, but not on all. Is there a rate limit active or so?

[ovirt-users] Can I Move a Fiber Channel Domain between different environments?

[Jacob Green]

We have two Ovirt environments, our existing environment is Ovirt 
4.1 And we want to migrate to our 4.2 environment, we chose this path 
because upgrading had a lot of issues for us, also we are migrating our 
cluster environment to a new IP scheme. So this made the most sense to us.


The question we have now is can we simply move an existing Fiber Channel 
domain from our Ovirt 4.1 environment to our 4.2 environment. I see 
information here that suggests we can, 
https://ovirt.org/documentation/admin-guide/chap-Storage/ however there 
is information further down in the document that seems conflicting or I 
am confused, I am willing to accept that.


*Near the top of the page I linked it says the following*

"Note:The export storage domain is deprecated. Storage data domains can 
be unattached from a data center and imported to another data center in 
the same environment, or in a different environment. Virtual machines, 
floating virtual disk images, and templates can then be uploaded from 
the imported storage domain to the attached data center. SeeImporting 
Existing Storage Domains 
for 
information on importing storage domains."


**Ok cool so I should be able to import the storage domain into a new 
environment? According to that information it would seem so.*

*

*However further down it says the following,*

"Reusing LUNs

LUNs cannot be reused, as is, to create a storage domain or virtual 
disk. If you try to reuse the LUNs, the Administration Portal displays 
the following error message:"


So I do not want to make a mistake, and remove my storage domain from my 
original ovirt environment just to find I cannot re add it to the new 
ovirt environment, and if I do that will I be able to import the VMs?



Thank you for any guidance on this topic, It would be much appreciated.


I guess the TLDR would be is the part pasted below of the linked 
documentation accurate for fiber channel?


"Data
Importing an existing data storage domain allows you to access all of 
the virtual machines and templates that the data storage domain 
contains. After you import the storage domain, you must manually import 
virtual machines, floating disk images, and templates into the 
destination data center. The process for importing the virtual machines 
and templates that a data storage domain contains is similar to that for 
an export storage domain. However, because data storage domains contain 
all the virtual machines and templates in a given data center, importing 
data storage domains is recommended for data recovery or large-scale 
migration of virtual machines between data centers or environments.
Important: You can import existing data storage domains that were 
attached to data centers with a compatibility level of 3.5 or higher."


Please forgive my confusion.

[ovirt-users] Ovirt VDI

[Hari Prasanth Loganathan]

Hi Team,

I created a VM which has one disk.
For this VM,  I created two Virtual Desktop (VDI_1 and VDI_2) using
open-UDS and it created successfully.

*Consider the following scenario* :

1) I took a console for VDI_1 and created a file in it using the console
2) I took the console for VDI_2 and checked whether the file created in
VDI_1 is available in it but as per the VDI concept it is not available

Could someone clarify the below use case,

Now when I looked at the Disk associated with the VDI, It seems the Disk of
the VM is same for the VDI_1 and VDI_2, so How does the file created in
VDI_1 is not reflecting in VDI_2?

Thanks,
Hari

[ovirt-users] Re: Ovirt Python - SDK

[Hari Prasanth Loganathan]

Thanks, Valentin and Brad.

I modified the UDS code to support ovirtSDK4, so everything works as
expected now.
Your thoughts are much appreciated.

Ansible 2.7.1 has been released in EPEL repositories. We are going to issue
an async update including oVirt Node by the end of this week.
CentOS hosts can be already updated consuming ansible 2.7.1.

[ovirt-users] Re: Memory usage is inaccurate on ovirt web manager.

[Martin Sivak]

Hi,

please notice the Shared Memory lines:

node2:
 Shared Memory:57%

vs.

node3:
 Shared Memory:98%

It seems you have overcommit enabled and KSM started deduplicating
pages. This frees memory when there are multiple VMs that use
identical pages. And node3 either has VMs that are similar or was just
faster when searching for identical pages.

Best regards

[ovirt-users] VM ramdomly unresponsive

[fsoyer]

Hi all,
I continue to try to understand my problem between (I suppose) oVirt anf 
Gluster.
After my recents posts titled 'VMs unexpectidly restarted' that did not provide 
solution nor search idea, I submit to you another (related ?) problem.
Parallely with the problem of VMs down (that did not reproduce since Oct 16), I 
have ramdomly some events in the GUI saying "VM x is not responding." For 
example, VM "patjoub1" on 2018-11-11 14:34. Never the same hour, not all the 
days, often this VM patjoub1 but not always : I had it on two others. All VMs 
disks are on a volume DATA02 (with leases on the same volume).

Searching in engine.log, I found :
2018-11-11 14:34:32,953+01 INFO

'Up'So it becomes up 15s after, and the VM (and the monitoring) see no downtime.
At this time, I see in vdsm.log of the nodes :

have no backups files :(.
But, luck in bad luck, the same event occurs this morning ! Same VM patjoub1, 
2018-11-13 08:01:37. So I have added the sanlock.log for today, maybe it can 
help.

IMPORTANT NOTE : don't forget that Gluster log with on hour shift. For this 
event at 14:34, search at 13h34 in gluster logs.
I recall my configuration :
Gluster 3.12.13
oVirt 4.2.3
3 nodes where the third is arbiter (volumes in replica 2)

The nodes are never overloaded (CPU average 5%, no peak detected at the time of 
the event, mem 128G used at 15% (only 10 VMs on this cluster)). Network 
underused, gluster is on a separate network on a bond (2 NICs) 1+1Gb mode 4 = 
2Gb, used in peak at 10%.

Here is the configuration for the given volume :
# gluster volume status DATA02
Status of volume: DATA02

[ovirt-users] Re: Ovirt Python - SDK

[Valentin Bajrami]

Hi Hari,

It would be best to create a venv(virtual environment) as follows:

python3 -m venv ovirtsdk

Then while in ovirtsdk venv directory you can use pip to install the
following packages:

- ovirt-engine-sdk-python==4.2.9
- pycurl==7.43.0.2 

Install these packages using:

pip install ovirt-engine-sdk-python==4.2.9 pycurl==7.43.0.2


Then, when you run your code use,  ovirtsdk/bin/python yourcode_py

Let me know if this works for you!

[ovirt-users] Re: Networking - How to pass all vlan (trunk) to a guest VM?

Unfortunately you are trying to implement an unsupported setup as discussed
already here:
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/O23ICVSO5SHTK5PX6ZFB7XB3ROWJOHAL/

* BTW, I have missed your responses. Please try to keep the ones who
participated in the thread on the email to/cc sections, it will improve the
chances the thread is tracked by them.

Thanks,
Edy.

I really depends if you are on hosted-engine or not and if on hyper
converged or not, if power management is configured and so on.
If not hosted-engine at all and no power management, I'd suggest:

shutdown:
1. shutdown all VMs
2. set host1 and host2 in maintenance mode from the engine (just to ensure
that all the locks on storage side are properly removed otherwise the
restart could take more time)
3. shutdown the engine host
4. shutdown hosts
5. shutdown your SAN

start:
1. start the SAN
2. start hosts
3. start engine host
4. remove hosts from maintenance
5. start VMs

[max zhang]

Thanks,I read the link  just now,But I would like to do it manually(Just 
because I am not often to do it).Would you like to tell me the sequence about 
shutdown?

Like as:
shutdown>>
step1:shutdown all VMs is running
step2:shutdown host1
step2:shutdown host2
step3:shutdown engine
step4:shutdown FCSAN storage
start>>
step1:start FCSAN storage
step2:start engine
step2:start host1
step3:start host2

I don't know whether I am right.

Hi,
of course you can manually simply shutdown the VMs on the storage domain
you want to migrate, detach it from the first engine and import it back in
the second one.
I'd also suggest to take a look to manageIQ which is the best response to
manage complex environments composed by multiple engine from a single panel.

[ovirt-users] what the sequence of shutdown in Cluster enviroment

[max zhang]

Hi man,There is always a doubt what the sequence of shutdown in Cluster 
enviroment.
The enviroment like as:
  engine.host.com
  node.host1.com
  node.host2.com
  FCSAN
host1 and host2 are in the same cluster.

By the way,after I shutdown all the host,what the  sequence of start in Cluster 
enviroment.

Best regards.
