[ovirt-users] Unable to upload image to disk - due to a network error

[Alan Aguinaga]

Hi. Is there a way to send an ISO to self hosted server? 

Because I 've been searching for help and a lot of people complaining about it. 

1 - What is the way to send ISOs to oVirt? Are there a command line tool to 
send ISOs to my server? 
"The ISO Uploader tool has been deprecated. Red Hat recommends uploading ISO 
images to the data domain with the Administration Portal or with the REST API. 
See Section 11.8.1, “Uploading Images to a Data Storage Domain” for details."
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html/administration_guide/sect-the_iso_uploader_tool

2 - ISO sending from portal worked for a smaller image. It could be done for OL 
7.9 with 4 GB. But I am trying to upload OL 8.9 ISO with 13.5 GB and it is not 
finishing. It is not resuming. It started to upload. I have a configured 
certificate installed and ok tested connection. 

I got this error: "Unable to upload image to disk 
a72b0da4-1bbb-453c-b846-701eef9761f6 due to a network error. Ensure 
ovirt-engine's CA certificate is registered as a trusted CA in the browser. The 
certificate can be fetched from" 
It started but not finished: "Sent 1732 of 12812 MB" 

This message is related to network not to certificate because it is installed 
otherwise it cannot even started to upload. 

Are there a user-friendly way to upload a ISO to a server using any command 
line tool? Latter versions I can send a ISO to a storage pool and it appears in 
server. Now I read it is impossible. Does it impossible by now? 

My is  4.4.10.7-1.0.25.el8. I am using NFS share and self hosted engine.

[ovirt-users] Affinity Labels in 4.4

[Alan G]

Can anyone explain how affinity labels work in 4.4?



I created a label containing a host and a VM. I had assumed that would require 
the VM to run on that host, but the VM continues to run on any host in the 
cluster.



I then checked the 4.4 documentation and it says that I need the filters module 
section of scheduling policy to contain Label, but there's doesn't appear to be 
a filter called Label.



Am I missing something?___

[ovirt-users] Re: VM disks Block device

[Alan G]

What exactly are you trying to achieve? LVM is just an implementation detail of 
oVirt so you shouldn't be interacting with on it on a normal basis.



If you want to share block devices between VMs then you can create a shareable 
disk.

LVM is used underneath the storage domain for disk management in kvm cluster on 
ovirt. VG which is the storage domain is visbile and active in all hosts in the 
same datacenter on ovirt. But, LV under this vg (that is the virtual disks of 
vms) is not active and the corresponding block devices of these LVs is not 
available on all hosts in cluster. 
I find only the running VMs LVs are active on the corresponding host. Is this a 
feature? 
 
Is it possible to get a corresponding block device and LV on all hosts in 
cluster?

[ovirt-users] Re: NIC Ordering

[Alan G]

My guess is that Foreman is deterministic, but the MAC addresses are allocated 
by oVirt and I don't know what rules are used there. For a long time it was 
fine and it worked as desired, but since we deleted a few VMs we have 
fragmentation in the MAC pool and now sometimes the "second" NIC gets allocated 
a lower MAC than the "first" NIC.



I probably need to capture the requests from Foreman to oVirt but not sure how 
to do that with it being HTTPS.



Your idea of using custom MTU size is interesting. thanks.

Hi,

the situation is significantly different in case you say that Foreman is not 
deterministic in supplying NICs via API.

So all this determinism in ‘first interface gets lowest MAC/lowest PCI’ is not 
helpful because you essential don’t know which interface becomes the first one.

In fact, I am not sure if your OS uses ‘lowest PCI’ or ‘lowest MAC’ for 
ordering, I think that ‘lowest PCI’ is much more widespread.

 

A few ideas:

    -I think that slightly more elegant: maybe the idea is to 
create VM with first NIC, then add second NIC and then start your VM?

-I am not sure what is your OS, but udev rules is a powerful mechanism to 
control NIC assignment.

In case you say that behaviour of Foreman can’t be addressed – you might change 
MTU by 1 byte for certain network (1499) then use this attribute to find that
 NIC

ATTR{mtu} or modify creation of VM to create one vNIC with link state=down and 
then use ATTR{operstate}

Konstantin

Perhaps it's more of a Foreman/API limitation.


 


In Foreman I provision two interfaces, that in the Foreman UI at least, have an 
ordering. Sometimes when they are provisioned in oVirt the "second" interface 
has a lower MAC
 than the "first" interface and so the ordering in Foreman is different to the 
ordering in oVIrt.


 


This breaks a bunch of stuff that relies on the networks being on specific

Hi,

Do I understand it correctly that:

    -your OS uses PCI addresses to order NICSs?

    -PCI addresses of NICs are in fact non-consistent between VMs?

So you boot VM1 (with NICs vNIC1 and vNIC2) and VM2 (vNIC3 and vNIC4) with same 
order in eg. API (->GUI) and you sometimes see different PCI addresses (vNIC2 
has higher
 PCI address than vNIC1; however vNIC3 has higher PCI address than vNIC4)? I am 
surprised about that…

My workaround today is unplug the NIC I want to be second, briefly power-up the 
VM so the "first" NIC gets assigned a PCI address, shutdown and re-plug the
 "second" NIC. On power-up the "second" NIC will be assigned a later PCI

It's just fiddly and can only be done on first boot. I was hoping for a more

Hi, 
I am working on a project and we would like to utilise (oVirt 4.5.) as the 
platform for our enterprise infrastructure. 
We have arrived at this juncture because of a range of considerations related 
to hardware and software availability and compatibility. 
 
My question is if there is on-going vendor \ professional support for oVirt 
moving forward, as one of my colleagues spoke with Red Hat, who stated they are 
going to end their support for the product. 
 
we will not gain security accreditation for our project unless we have 
professional support available, community support only is not sufficient, 
 
Any ideas of firms available for a support contract for oVirt 4.5.0?

[ovirt-users] Create VM with Python SDK

[Alan G]

Hi,

Trying to create a VM while attaching an existing disk. I can create the VM 
then attach the disk with an additional call, but I thought it should be 
possible to do it in one hit?


My code is

vm = vms_service.add(

    types.Vm(

    name='alma8.7',

    description='AlmaLinux 8.7 CIS Packer image',

    cluster=types.Cluster(

    name='Default',

    ),

    type=types.VmType('server'),

    template=types.Template(

    name='Blank',

    ),

    disk_attachments=[types.DiskAttachment(

    disk=types.Disk(id = "0532e728-a1fb-4ff8-a4f3-0702fc876fce"),

    bootable=True,

    active=True,

    interface=types.DiskInterface.VIRTIO,

    )]

    ),

)





This request returns no error but the disk isn't actually attached to the 
created VM.___

Ah, I didn't appreciate that.



My main concern with running the OVA export was getting a consistent image. The 
machine I am exporting has a large disk which will take some time to export and 
I didn't want to have to shut the machine down for the duration of export 
operation.



I see now, when I trigger an export that a snapshot is created. Thanks.

The fact you're asking specifically about the image makes me wonder 
what's the reason for asking that 
If you look for a way to create an OVA directly from an existing 
snapshot then no, it's not possible. You'd need to provision a 
VM/template from the snapshot and export it to an OVA. 
If you don't want the export operation to operate on the active 
volume(s) of the VM then unless the VM is configured with MBS (managed 
block storage) disk, the system creates a snapshot first and exports 
the volumes that are associate with the snapshot to the OVA (so it 
doesn't use the active volumes)

[ovirt-users] Re: what are the steps to swap/upgrade/reboot my main storage domain with minimum downtime

[Alan G]

Depends what you mean by "sync" and "swap".



If you can keep the same NFS endpoint, but swap-in your upgraded storage under 
the hood then I think you can do as you propose. Stop all VMs, put the storage 
domain in maintenance, make you changes and bring the domain out of maintenance.



However, if you're moving to a different NFS server, or even different path on 
the same server then I think the answer is no. In this scenario you'd need to 
create a new domain and move each vdisk across.

Sorry, I missed the fact that you also have HE in the same domain.



I think the previous statement still stands. But you'd be advised to stop the 
ovirt-ha-agent and ovirt-ha-broker on all hosts as well.

[ovirt-users] Re: [OLVM] Host non responsive after installation

[alan]

Fixed. Thanks for the help! This is specific to our CSP, but some thoughts that 
might help:
- Utilities like tcpdump were helpful in analysis. It ultimately ended up being 
network issues (rather than SSL or something in the oVirt setup).
- In my environment, the host had two NICs, and the FQDN of the host resolves 
to the IP address on the first NIC. However, it needed to use the network that 
the second NIC was connected to. So adding the host by this IP address instead 
of the FQDN worked (or modifying the hosts file to resolve the FQDN instead of 
using DNS).

[ovirt-users] Re: [OLVM] Host non responsive after installation

[Alan Daniels]

Some new information: I found that the VDSM traffic (anything not SSH) was
being blocked by the default network security rules (not on the host).
After fixing this, I am still unable to add a host though.

If I try
vdsm-client -a  Host getCapabilities
I get this error:
[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:618)

Rather than the previous error of just timing out. So maybe there is still
an issue with the certs.

When I add the host, it now fails with:
VDSM GPU2-2 command HostSetupNetworksVDS failed: Message timeout which can
be caused by communication issues
and I can't SSH into the host anymore.

If I restart the host, it becomes NonOperational because ovirtmgmt is
missing.

Thanks!
- Alan

[ovirt-users] [OLVM] Host non responsive after installation

[alan]

I am using Oracle Linux Virtualization Manager, following this guide: 
https://docs.oracle.com/en/virtualization/oracle-linux-virtualization-manager/getstart/manager-install.html

After adding a host to the engine, the host becomes non responsive due to 
network errors:
engine.log

[ovirt-users] Re: supervdsm failing during network_caps

[Alan G]

Looking back in the logs, in fact the first error we get is Out of memory. So 
it seems we're hitting https://bugzilla.redhat.com/show_bug.cgi?id=1623851



It's not clear from the ticket. Is there an explicit fix for this is 4.4, or 
the problem just kind of went away?

This occurs on both nodes in the cluster. A restart of vdsm/supervdsm will sort

I can find almost no information on this. The best I could find was this 
https://linuxlizard.com/2020/10/18/message-sequence-number-mismatch-in-libnl/

issue in that the nl sequence numbers are getting out of sync and 
closing/re-opening the nl socket (aka restart vdsm) is the only way to resolve.



I've completely hit a brick wall with it. We've had to disable fencing on both 
nodes as sometimes they get erroneously fenced when vdsm stops function 
correctly. At this point I'm thinking about replaced the severs with different 
models in-case it's something in the NIC drivers...

[ovirt-users] Custom firewalld zones?

[Alan G]

Hi,



Is there any support for custom zones in firewalld? The only reference I can 
find is this from years ago



https://lists.ovirt.org/pipermail/users/2015-May/032791.html



We're trying to put ovirtmgmt into a zone other than the default zone, but vdsm 
keeps reverting the config whenever it rewrites ifcfg-ovirtmgmt, with the 
result that the host becomes unreachable.

[ovirt-users] Re: affinity/pool/fencing ?

[Alan G]

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.



Regards



Nar

[ovirt-users] Re: change lun for hosted_engine use?

[Alan G]

The "long-winded" way is the only way I know of doing it.



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



Providing you plan in advance I don't think it's really that onerous. And it 
means you have a stable system going forward...

I currently have a self-hosted engine, running in a dedicated ISCSI storage

I'd like to change the backend hardware for the storage. 
 
i think there's some longwinded and complicated method of shutting down the 
engine, backup, creating a NEW one, restore, and whoknowswhat. 
 
I was wondering though, if maybe there's a way to just add an iscsi lun to the 
storage domain, and tell ovirt, "Hey, move the stuff over to that other lun" 
? 
 
Ive added the new lun already :) havent found a reference to move the files' 
residence though. 
 
If it helps, my end goal is to remove that lun completely.

[ovirt-users] Re: Is there a way to access VM data that is stored using iscsi block storage outside of the ovirt platform ?

[Alan G]

You can definitely build a bare metal Engine and do a DB restore onto it. I've 
done this before when I had problems. Obviously you will need a sane backup 
from your hosted engine.



I'm surprised the NFS build didn't work though. You probably need to remove the 
stale iSCSI hosted_storage domain and then I think it will automagically 
discover the new NFS one and then everything should start working.

Can I build an new ovirt standalone engine on a new bare metal remote server 
and connect to the hosts and start up the domain ? 
I would be interested in your thoughts. 
The problem with rebuilding the hosted-engine is that it cannot reuse the lun 
dedicated for the hosted-engine. I have tried to rebuild using NFS but it 
complains about not seeing the master domain

When running from the terminal you are unconfined, hence it runs without error.



Probably your only option is to create custom policy to allow this. Although I 
would question why the log file you are reading is cron_log_t and not var_log_t.

You're right, the hugepages are considered as allocated memory and it is a bug.

[ovirt-users] Re: Ovirt engine showing wrong host's memory usage

[Alan G]

Maybe there is some subtlety here that I am missing?



Taking one of my hosts as an example (running 4.2 - not sure if the code has 
changed in 4.3?)



$ head -5 /proc/meminfo 

MemTotal:   263695240 kB

MemFree:    80087284 kB

MemAvailable:   137272368 kB

Buffers:   79620 kB

Cached:  7758272 kB



While in the oVIrt GUI it reports



257514 MB total

172534 MB used

84980 MB free



And from the Host page it reports memory utilisation as 67%, which roughly 
equates to used / total.



(total - available) / total would give a value more like 50%.

Look at Network Filters in the vNIC profile for the network. I haven't tested

[ovirt-users] Issues encountered performing HE install on 4.3

[Alan G]

Hi,



I hit a few issues while performing a recent HE install of 4.3. While I managed 
to find solutions/workarounds to all the problems I thought I might share them 
here

* As defined in the Ansible defaults the temp dir for building the local HE VM 
is /var/tmp. I was 80M short of the required space and there did not appear to 
be a (supported) way to specify a different location. I ended up having to do a 
bind mount of /var/tmp to get me through the install. Would be nice to be able 
to specify a custom location.



* Permissive umask required. Our CIS CentOS 7 build requires that default umask 
is 027. This breaks the installer as it creates the VM image under /var/tmp as 
root and cannot then access it as qemu user. As the temp files are cleaned up 
on failure it took me a while to track this one down. My solution was to 
temporarily set the umask to 022 for the session while running the installer. 
It would be nice if the installer either handled this by doing a chmod/chown as 
required, or at least doing a umask pre-check and failing with a meaningful 
error.



* SSH root login required on host. Again for CIS we have "PermitRoologin no" 
configured in sshd. This means the add host task fails on the Engine, but 
instead of a hard failure we get a timeout on the installer. Which left me 
chasing some imagined routing/bridging/DNS issue. Eventually I realised I could 
get to the engine logs and found the issue but took several hours. Would be 
nice if the installer could either support a sudo option or at least perform a 
root login pre-check and fail with a meaningful error.



Thanks,

[ovirt-users] Re: oVirt behavior with thin provision/deduplicated block storage

[Alan G]

Thanks for the clarification on this. I've realised my mistake now - I need to 
configure the storage array to report the LUNs as larger than they physically 
are (to account for the expected de-dup ratio).  I was expecting oVirt to 
magaically know about this, which when thinking it through is not really 
technically possible.

[ovirt-users] Re: oVirt behavior with thin provision/deduplicated block storage

[Alan G]

I'm not really concerned about the reporting aspect, I can look in the storage 
vendor UI to see that. My concern is: will oVirt stop provisioning storage in 
the domain because it *thinks* the domain is full. De-dup is currently running 
at about 2.5:1 so I'm concerned that oVirt will think the domain is full way 
before it actually is.



Not clear if this is handled natively in oVirt or by the underlying lvs?

oVirt does not know about the underlying block storage thin provisioning

You will have to use the underlying storage separately to learn about the 
actual allocation.



This is unlikely to change for legacy storage, but for Managed Block Storage 
(conderlib) we may have a way to access such info.



Gorka, do we have any support in cinderlib for getting info about storage 
alllocation and deduplication?

[ovirt-users] oVirt behavior with thin provision/deduplicated block storage

Hi,



I have an oVirt cluster with a storage domain hosted on a FC storage array that 
utilises block de-duplication technology. oVirt reports the capacity of the 
domain as though the de-duplication factor was 1:1, which of course is not the

[ovirt-users] supervdsm failing during network_caps

I have issues with one host where supervdsm is failing in network_caps.



I see the following trace in the log.

A restart of supervdsm will resolve the issue for a period, maybe 24 hours, 
then it will occur again. So I'm thinking it's  resource exhaustion or a leak 
of some kind?



Running 4.2.8.2 with VDSM at 4.20.46.



I've had a look through the bugzilla and can't find an exact match, closest was 
this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be 
a RHV only fix.

[ovirt-users] Re: Moving HostedEngine

[Alan]

The installation will fail if you attempt to install HE into an existing 
storage domain (or worse, it will corrupt the domain).



As per the docs you will need a dedicated domain of at least 74GB for 
hosted_storage.

I have the same issue and haven't been able to find a solution. It seems that 
the initial LUN is hard coded into /etc/ovirt-hosted-engine/hosted-engine.conf

thanks. This happens to be a prefect way to add a storage domain with all the

Good day Francesco,

If I understand you correctly you can try the following via GUI:



1) Go to "Storage" menu.

2) Go to "Domain" menu.

3) Press "New Domain" button. The "New Domain" window will open.

4) Choose "iSCSI" from the "Storage Type" dropdown list.

5) At the "Discover Targets" section:

    5a) For each path:

        5a1) Enter path at the "Address"  field.

        5a2) Press "Discover" button.

    5b) Press "Login All" button.



Hope it helps.

[ovirt-users] Re: ovirt hosted-engine on iSCSI offering one target

[Alan]

I had this situation a while back. As I recall ovirt has no way to selectivity 
un-mount devices exposed via an iSCSI target.

So the problem you could hit is that if you tried to put your data domain into 
maintenance it would nuke any other domains that are accessed through that 
target (e.g. your hosted-engine domain).

For me the situation was even worse as I was doing boot-from-SAN as well. So I 
would loose the boot disk.

On my NetApp I ended up creating three targets: BFS, hosted-engine & data.

Hi,



We have an oVirt Platforme using the 4.1 version.



when the platforme was installed, it was made of :

- Two HP Proliant DL380 G9 as hypervisors

- One HP MSA1040 for iSCSI

- One Synology for NFS

- Two switches, one for network/vm traffic, the second for storage traffic.



The problem : the hosted-engine domain was created using iSCSI on the HP MSA. 
The problem is that this disk array does not give the possibility to create 
different targets, it presents just one target.



At that time we create both the hosted-engine and the first data domain using 
the same target, and we didn't pay attention to the information saying "if you 
are using iSCSI storage, do not use the same iSCSI target for the shared 
storage domain and data storage domain".



Question : 

- what problems can be generated by this (mis-)configuration?

- Is this a must to do (correct) configuration.





Regards.

[ovirt-users] Cleaning up after failed task

[Alan G]

Hi,



Yesterday I had an AddDisk operation fail. The task is no longer running on the 
SPM but it's stuck in the engine DB and the failed disk is now locked. I've 
tried to clean it out using taskcleaner.sh, but either I'm using it incorrectly 
or it doesn't handle my specific scenario.



There were no running tasks (-T returned empty set). There were two commands 
(-o) which I then removed (-r) but the Engine UI is still reporting the tasks. 
Possibly because step table still reports non finished steps.



engine=# select step_id,start_time,end_time,status from step order by 
start_time; 

   step_id    | start_time |  
end_time  |  status

[ovirt-users] Re: Cluster Un-stable since power outage

[Alan G]

So, after a week of bashing my head against a wall we finally tracked it down. 

One of the developers was using the hosts for extra processing power and in the 
process he periodically turned up an sshfs mount, when this appeared in 
/etc/mnttab it broke vdsm and caused the error below. So was unrelated to the 
power outage.

This is in 4.2 - if I re-create in 4.3 I'll file a bug, I think the parser 
really should be a but more robust than this.

Was your hyper converged and is this storage gluster based?

Your error is DNS related, if a bit odd. Have you checked the resolv.conf 
configs and confirmed the servers listed there are reachable and responsive? 
When your hosts are active, are they able to mount all the storage domains they 
need? You should also make sure each HA node can reliably ping your gateway IP, 
failures there will cause nodes to bounce.



A starting place rather a solution, but the first places to look. Good luck!

[ovirt-users] Replace Engine Self-Signed Certificate

Hi,

I'm trying to replace the self-signed certificate in the engine.

I updated the four files listed here

http://www.ovirt.org/develop/release-management/features/infra/pki/

But on restarting Apache and logging in I get the following error,
"sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find
valid certification path to requested target"

What am I missing?

Thanks,

Alan

[ovirt-users] oVirt 3.6.4 / PXE guest boot issues

[Alan Griffiths]

A explanation/work-around for this issue raised back in April.

It seems that if, in UCS, you configure a vNIC with a single native VLAN it
will still add an 802.1q header with tag 0 - possibly to do with QoS. And
this extra header prevents iPXE from parsing the DHCP response.

The solution for me was to present all VLANs on a single trunked vNIC to
the blade and configure VLAN tagging as per normal. The result is the tags
are stripped off the packets before being passed to the VM and DHCP now
works.

The same issue applies to VM-FEX as packets coming off the VF will have the
802.1q header. The only solution I can see here is to configure a bridged
interface for initial build of the VM and then switch to VM-FEX afterwards.

I found a discussion on the iPXE mailing list about addressing the vlan 0
issue, but I could see no agreed solution.

[ovirt-users] Hosted Engine Restore Issues

[Alan G]

Hi,



Trying to re-deploy Hosted Engine into a new storage domain. "hosted-engine 
--deploy  --noansible" has completed and the engine is up, but I cannot remove 
the existing hosted_storage domain to allow the new one to be imported.



I cannot remove the domain until the old HostedEngine VM is removed, but I 
cannot remove that as it has Delete Protection enabled. Any attempt to remove 
delete protection errors with "There was an attempt to change Hosted Engine VM 
values that are locked". How is this process supposed to work?

[ovirt-users] Cannot get IPMI fencing to work on CIMC

Hi,



I have some Cisco C-220M4 servers with CIMC (not connected to UCS fabric).



I can get the fencing to work on the command line like this



fence_ipmilan -a XXX -l YYY -p ZZZ --hexadecimal-kg=ABC -o status -P



But when I try to configure & test in the Engine UI I get, "Test failed: 
Internal JSON-RPC error".



Obviously the wrong parameters are being passed to the script, but I cannot 
find a log anywhere which will show me the parameters being used. Anyone else 
got IPMI working on CIMC?

qemu-img convert process (if you are doing cold migration), unless there is a

Hi,



I accidentally triggered a storage migration for a large vdisk that will take 
some hours to complete. Is there a way to cleanly cancel the task, such that 
the vdisk will remain on the original domain?



Thanks,

[Alan G]

It's cold migration on 4.1.9.


So I just kill this process?

[ovirt-users] LUN ID Change on Storage Domain

[Alan G]

Hi,

I made an error when provisioning a new FC storage domain and gave it LUN ID 0 
by mistake. I now need to move it to another ID.

Can I do this: -

1. Shutdown all VMs on the domain.
2. Put the domain in maintenance.
3. Change the LUN ID.
4. Force SCSI rescan on every host.
5. Bring the domain out of maintenance.


Will oVIrt still recognise the domain on a different LUN ID?



Thanks,

[ovirt-users] help with non-standard LDAP authentication

[alan . edwards]

I am using an LDAP configuration that either does not expose or contain a 
nsUniqueId value for Groups.  Many of the standard schema fieldnames have been 
changed to contain a company prefix.  I managed to update the profiles enough 
to have the user authentication work properly & search for the LDAP groups now. 
 But I am unable to add the LDAP group due to the following error: 

Caused by: org.postgresql.util.PSQLException: ERROR: null value in column 
"external_id" violates not-null constraint
  Detail: Failing row contains (dad4b561-6aaa-4e7c-9887-997ba8142d3f, ADMGROUP, 
REALM-authz, null, null, o=BASE)

I've checked the profiles to see if I could possibly remap the nsUniqueID value 
for Groups (thinking of using either the gid or dn value), but I do not see how 
I can have a different value for groups from users.  I have seen a similar 
thread from 3 years ago, but it appeared to have been a different cause.

Any advice or suggestions?  The main goal I am attempting to achieve is to use 
an existing LDAP user group to control who has access to the system such that 
we do not have to add users manually.  

Thanks,
Alan

[ovirt-users] iSCSI Boot from SAN

[Alan G]

Hi, I'm setting up a lab with oVirt 4.2. All hosts are disk-less and boot from 
a NetApp using iSCSI. All storage domains are also iSCSI, to the same NetApp as 
BFS. Whenever I put a host into maintenance vdsm seems to try to un-mount all 
iSCSI partitions including the OS partition, causing the host fail. Is this a 
supported configuration? Thanks, Alan___

storage and hosted engine. Last night a host went unreachable due to a 
driver/firmware issue with the NIC card. The Engine spotted this, the host was 
fenced and everything behaved as expected. However, it got me thinking - if the 
affected host had been the one running the Engine, what would have happened? 
I'm assuming the Engine would have failed liveness check on the other hosted 
engine hosts and they would attempt to start the Engine. But as the "failed" 
host still had access to the storage (I believe the HBA was still working) then 
they would not be able to get a lock on the storage. In which case I'm in a 
catch-22, the Engine cannot fence the failed host because its network is 
isolated, but the Engine cannot be restarted else where until the failed host 
is fenced. At this point it requires human intervention to fence the failed 
host. Is my understanding correct on this? If so is there any way to mitigate 
this risk? ovirt-ha-agent implements a specific test for this kind of failures 
continuously trying to ping a specific IPv4 address (usually the network 
gateway) to check network connectivity on each involved host. On failed pings 
each host penalises itself by a certain amount of points; the HA score of each 
host is written into the hosted-engine metadata volume on the shared storage so 
each host can also see the score of other hosts and in your case this would 
work since all the hosts can still access the storage via FC. Once the 
difference between the score of the host running the engine VM and the best 
candidate host is large enough a migrate to best host (or shutdown and restart 
there if not possible as in your case) action will be triggered. If you want, 
you can easily try to reproduce this scenario.   Thanks, Alan

[ovirt-users] Question on HA failure scenario

[Alan G]

Hi, I have 4.1 cluster with FC block storage and hosted engine. Last night a 
host went unreachable due to a driver/firmware issue with the NIC card. The 
Engine spotted this, the host was fenced and everything behaved as expected. 
However, it got me thinking - if the affected host had been the one running the 
Engine, what would have happened? I'm assuming the Engine would have failed 
liveness check on the other hosted engine hosts and they would attempt to start 
the Engine. But as the "failed" host still had access to the storage (I believe 
the HBA was still working) then they would not be able to get a lock on the 
storage. In which case I'm in a catch-22, the Engine cannot fence the failed 
host because its network is isolated, but the Engine cannot be restarted else 
where until the failed host is fenced. At this point it requires human 
intervention to fence the failed host. Is my understanding correct on this? If 
so is there any way to mitigate this risk? Thanks, Alan___

[ovirt-users] Re: VM create with network interface via the API

[Alan Bunch]

"You can add the vNIC after VM is created, but before the VM is booted the 
first time."

Sometime you just need someone to point out the obvious.

For some reason it just never occurred to me to add the nic BEFORE the first 
start. This is my first time using api to control vms and I am still very low 
on the learning curve.

Thank you so much for pointing me in the correct direction.

[ovirt-users] VM create with network interface via the API

[Alan Bunch]

Hello all and thank you in advance for your help.

I have been able to work out how to add vm via a call to the vms API.   I am 
passing in a template via the api call and that is working.  I do not have a 
network installed in the template. My use case for that was to hit “New vm”, 
fill in the hostname and network and let cloud-init set the hostname.  That way 
I can create a new vm with just a few clicks.  

What I can’t seem to figure out is how to define the network interface in the 
add vm api call.   It looks like I should have to add the network interface in 
a second call after creation.If I add the interface in the  
 section for cloud-init I seems to have a chicken and egg 
problem.  When I add the   section and the data for the ip 
address, netmask, default gateway, I get;


[Cannot add VM. Static IPv4 address is missing in cloud-init 
configuration.]
Operation Failed


That would seem to indicate to me that I need and interface before I can 
configure it.  That makes sense.  But how do I get an interface before I create 
the vm ?

What might I be missing?

The desired result is create a vm and set the hostname and ip info via the api 
so that I get a fully formed vm connected to the network.  That gets me to the 
point of being able to download build scripts to install and start puppet.

[ovirt-users] nfs 4.2 support

[Alan Griffiths]

Hi,

I noticed that when mounting nfs domains in ovirt 4.1 using
auto-negotiate it settles on v4.1.

Is this due to lack of live storage migration as referenced in this bug

https://bugzilla.redhat.com/show_bug.cgi?id=1464787

Are there other known issues with 4.2 support?

Thanks,

Alan

[ovirt-users] Engine AAA LDAP startTLS Protocol Issue

[Alan Griffiths]

Hi,

Trying to configure Engine to authenticate against OpenLDAP and I seem
to be hitting a protocol bug.

Attempts to test the login during the setup fail with

2018-02-07 12:27:37,872Z WARNING Exception: The connection reader was
unable to successfully complete TLS negotiation:
SSLException(message='Received fatal alert: protocol_version',
trace='getSSLException(Alerts.java:208) /
getSSLException(Alerts.java:154) / recvAlert(SSLSocketImpl.java:2033)
/ readRecord(SSLSocketImpl.java:1135) /
performInitialHandshake(SSLSocketImpl.java:1385) /
startHandshake(SSLSocketImpl.java:1413) /
startHandshake(SSLSocketImpl.java:1397) /
run(LDAPConnectionReader.java:301)', revision=0)

Running a packet trace I see that it's trying to negotiate with TLS
1.0, but my LDAP server only support TLS 1.2.

This looks like a regression as it works fine in 4.0.

I see the issue in both 4.1 and 4.2

4.1.9.1
4.2.0.2

Should I submit a bug?

Thanks,

Re: [ovirt-users] Why was HE Install made OVA only?

[Alan Griffiths]

I was building my own image, using Foreman, Puppet and PXE. There's a
specific partitioning schema I'm required to use in my environment and
building my own image from Kickstart is by far the easiest way to
achieve this.

I can appreciate that in most scenarios the OVA install is the
best/easiest option, but it would have been nice to keep PXE and ISO
options.

Re: [ovirt-users] ovirtmgmt network

[Alan Griffiths]

I think you would need an IP address on IF2, otherwise the HE cannot
communicate with the host.

If you have an entry in /etc/hosts that resolves the FQDN of the host
to the IP on IF2 then I think the setup script should create the
ovirtmgmt bridge there.

Re: [ovirt-users] VM remote noVNC console

[Alan Griffiths]

I have this working through an SSH tunnel, although it adds some extra steps.

1. Figure out which port your VM console is bound to (5900 + offset).
2. SSH to the hypervisor tunneling a local port to that remote console port.
3. Click on the console link in the Engine and locally save the vv file.
4. Edit the vv file; change host to localhost and port to whichever
port you configured for the local side of the tunnel.
5. Save and run the vv file with your SPICE client.

You have two minutes to connect from downloading the vv file before
the password expires.

[ovirt-users] Ovirt 4.0 and EL 7.4

[Alan Griffiths]

Hi,

Is 4.0 supported/known to work on CentOS 7.4?

I've just tried to upgrade one of the hosts in my lab from 7.3 to 7.4
and now vdsm-network fails to start with

vdsm-tool: libvirt: XML-RPC error : authentication failed: authentication failed

To even get this far I had to exclude gluster packages as 7.4
introduces 3.8 but ovirt 4.0 repo is still on 3.7.

So, more generally. If I'm on ovirt 4.0, gluster 3.7 and EL 7.3. What
is the best ordering for getting to ovirt 4.1 and EL 7.4?

Thanks,

Alan

[ovirt-users] Engine Backup/Restore Question

[Alan Griffiths]

Hi,

Currently testing my recovery plan for HE failure.

I run a hosted engine, but in the event of some failure of the engine VM i
want to be able to quickly restore the engine to a standalone host running
independent of Ovirt (in this case a VM running on ESXi).

On a dry run I restore the backup onto the ESXi VM and run engine-setup. At
this point it fails with an error that I am not in Global Maintenance mode.

If I put the cluster into maintenance mode before performing the backup
then it works correctly. So is it necessary to do this on every backup? I
can find nothing in the documentation detailing this as a requirement?

Alternatively it seems I can manually update the ha_global_maintenance
column in the vds_statistics table before running engine-setup, but not
sure of the implications of doing this.

ovirt-4.0.6.3

Thanks,

Alan

Re: [ovirt-users] Ovirt 4.1 testing backup and restore Self-hosted Engine

[Alan Griffiths]

As I recall (a few weeks ago now) it was after restore, once the host had
been registered in the Manager. However, I was testing on 4.0, so maybe the
behaviour is slightly different in 4.1.

Can you see anything in the Engine or vdsm logs as to why it won't remove
the storage? Perhaps try removing the stale HostedEngine VM ?

Re: [ovirt-users] Inter Cluster Traffic

I am planning to live migrate VMs. From my testing this works fine
providing cross cluster hosts can talk to each other and they share a
common migration network.

Re: [ovirt-users] Inter Cluster Traffic

[Alan Griffiths]

Just found this in the RHV docs. I think sections 2.8 to 2.12 cover
everything you could wish to know about SPM process. It made it clear for
me anyway. Once SPM is elected then all communication is via the storage
domain, no TCP/IP comms required.

Re: [ovirt-users] Inter Cluster Traffic

[Alan Griffiths]

It's my understanding that when you activate a host part of the process is
to verify that it can connect to all active storage domains. If it cannot
connect to any domain then it will refuse to go to the "up" state. In my
case the storage domains are FC so completely outside the TCP/IP stack.

[ovirt-users] Inter Cluster Traffic

[Alan Griffiths]

Hi,

I'm in the process of building a second ovirt cluster within the default
DC. This new cluster will use the same storage domains as the original
cluster, and I will slowly migrate VMs from the old cluster to the new.

Given that the old and new cluster hosts have a firewall between them I
need to ensure that all relevant ports are open, with particular attention
to the correct operation of SPM.

Is it sufficient to open TCP ports 16514 and 54321 to achieve this?

Thanks,

Alan

Looking at vdsmd.service on one of my 4.0 hosts.

Requires=multipathd.service libvirtd.service time-sync.target \
 iscsid.service rpcbind.service supervdsmd.service sanlock.service \
 vdsm-network.service

Are all these services present and running?

Re: [ovirt-users] [EXTERNAL] Re: Host stuck unresponsive after Network Outage

[Alan Griffiths]

Is rpcbind running? This is a dependency for vdsmd.

I've seen issues where rpcbind will not start on boot if IPv6 is disabled.
The solution for me was to rebuild the initramfs, aka "dracut -f"

[ovirt-users] Ovirt installation planning question

[Alan Bunch]

Hello all,

I have a question about the initial setup for ovirt. I have 3 nodes
that I am about ready to install a hyper converged setup using Gluster
for storage and hosted-engine.

My question is this:

What does the networking setup need to look like at install time ? Do
I need to setup all of the bonds, vlans and bridges before I start the install
or should I just set an ovirtmgmt bond/vlan/bridge and setup the rest of the
networking inside of ovirt. I expect to need 3 or 4 networks/vlan to match
my existing networks to attach vm's to.

Any help or pointers would be appreciated.

Thank You

Re: [ovirt-users] Ovirt adding routes

[Alan Griffiths]

Thanks for the clarification, I see now why it's not working. In the GUI
there is no gateway configured for ovirtmgmt network on my single host.
However I can't add one as the network is "in use" by the HostedEngine.
Other than adding a second host is there anyway to work around this?

[ovirt-users] Ovirt adding routes

[Alan Griffiths]

Hi,

When installing an ovirt host I got these routes automatically added

default dev ovirtmgmt  table 2886865805  scope link
172.18.19.128/26 via 172.18.19.141 dev ovirtmgmt  table 2886865805

What is their intended purpose? It seems to be stopping packets from being
correctly routed to the local gateway.

Thanks,

[ovirt-users] KVM Import with Thin Provisioning

[Alan Griffiths]

Hi,

I don't seem to be able create thin provision disks when importing from
KVM. Once import is complete the disk allocation policy is reported as
thin, but the actual size is in fact slightly larger than the virtual size.

For example, original qcow2 file size - 6G. Virtual size - 1024G. Imported
actual size (according to Engine GUI) 1126G.

Is this a known issue?

Running 4.0.4.

[ovirt-users] Resolving host non_responsive

[Alan Griffiths]

Hi,

Following a short network outage a couple of HE hosts are reported as
non_responsive in the engine. Storage was not affected and the VMs continue
to run on those hosts. Is it possible to bring the hosts back under
management without disrupting the running of the VMs? Is it as simple as
confirming host has rebooted?

Thanks,

Re: [ovirt-users] VDSM overwrites network config

[Alan Cowles]

Hey Dan,

Here is a layout of my environment setup, and the primary issue I have run
into, hopefully it helps to clear up the confusion.

Configure 2 hosts identically, eth0, eth1, eth0.502 (mgmt), eth1.504 (NFS)
and do the self-hosted engine install on one host.
As part of the install you have to identify the network that rhevm needs to
go on, and the network you need to mount your first NFS storage domain
from. In this case, eth0.502, and eth1.504 respectively.
That host, and the rhev-m hosted engine come up, however if you notice,
under Networks for the default datacenter, only rhevm exists as an actual
network.
You need to create a new network for NFS, in order to mount ISO/Data
storage domains, even though the engine setup has already mounted NFS via
eth1.504.
When you go to assign this new network from the engine, you cannot place it
on the eth1.504 only directly on eth0 or eth1 iteself.
Thus I have to be sure to tag that network in the rhev-m engine
When the tagged NFS network is placed on eth1, it looks like it breaks the
already existing NFS mount that supports the hosted engine, and causes
items to be non-responsive.
Rebooting the host at this stage, items still don't come up correctly and
the hosted engine remains down.
If I console to it, and manually setup the eth0 & eth1 interfaces, eth0.502
& eth1.504 VLANS,  and rhevm & NFS bridges, and reboot the host, the host
and the engine come up wonderfully with the defined networks vlan tagged,
and placed on the appropriate tag interfaces.

I then go to deploy a 2nd host as an additional hosted engine, and find
that I can select eth0.502 for rhevm and eth1.504 for nfs during the deploy
stages. But when it gets to the stage where it requires to you define the
networks that exist in the current cluster in order to activate the host
and proceed, I'm stuck in the same spot with applying networks, I can only
place them on the eth0/eth1 interfaces. I select ignore to exit the hosted
engine deployment wizard, and attempt to manually apply them, hoping to
repeat the steps from node 1 but was finding myself in a pickle because
starting VDSM would overwrite the network configs I had defined manually.
Why it does this on one host, and not on the other still perplexes me.

What I ended up doing once my primary host was rebuilt using the
appropriate bridges and vlan tagged interfaces, was reinstalling my 2nd
host completely, and configuring it as a self-hosted engine additional
host. This time it imports the network config from the first host
completely here, and I wind up with all tagged interfaces working correctly
and VDSM running as designed.

I guess the thing that bothered me mainly is the functionality in assigning
the networks in rhev manager, as it shows the vlans as sub-interfaces of
eth0/eth1, but doesn't let you assign networks to them, and the odd
behavior of VDSM overwriting configs on one host, but not the other?

I'll admit the setup I have is convoluted, but it's what I have to work
with for this project.

Thank you very much for the time and advice thus far.

[ovirt-users] VDSM overwrites network config

[Alan Cowles]

Hey guys,

I'm in a lab setup currently with 2 hosts, running RHEV-3.5, with a
self-hosted engine on RHEL 6.9 servers. I am doing this in order to plot
out a production upgrade I am planning going forward to 4.0, and I'm a bit
stuck and I'm hoping it's ok to ask questions here concerning this product
and version.

In my lab, I have many vlans trunked on my switchports, so I have to create
individual vlan interfaces on my RHEL install. During the install, I am
able to pick my ifcfg-eth0.502 interface for rhevm, and ifcfg-eth1.504
interface for NFS, access the storage and create my self-hosted engine. The
issue I am running into is that I get into RHEV-M, and I am continuing to
set the hosts up or add other hosts, when I go to move my NFS network to
host2 it only allows me to select the base eth1 adapter, and not the VLAN
tagged version. I am able to tag the VLAN in the RHEV-M configured network
itself, but this has the unfortunate side effect of tagging a network on
top of the already tagged interface on host1, taking down NFS and the self
hosted engine.

I am able to access the console of host1, and I configure the ifcfg files,
vlan files, and bridge files to be on the correct interfaces, and I get my
host back up, and my RHEV-M back up. However when I try to make these
manual changes to host2 and get it up, the changes to these files are
completely overwritten the moment the host reboots connected to vdsmd
start-up.

Right now, I have vdsmd disabled, and I have host2 configured the way I
need it to be with the rhevm bridge on eth0.502, the NFS bridge on
eth1.504, and my VMNet "guest" bridge on eth1.500, however that leaves me
with a useless host from RHEV standards.

I've checked several different conf files to see where vdsmd is pulling
it's configuration from but I can't find it, or find a way to modify it to
fit my needs.

Any advice or pointers here would be greatly appreciated. Thank you all in
advance.

hosted-engine. Gluster is setup and the volumes are mounted.

My question is this:
What does the networking setup need to look like at install time ? Do I need to 
setup all of the bonds, vlans and bridges before I start the install or should 
I just set an ovirtmgmt bond/vlan/bridge and setup the rest of the networking 
inside of ovirt. I expect to need 3 or 4 networks/vlan to match my existing 
networks to attach vm's to.

Any help or pointers would be appreciated.

Thank You

Re: [ovirt-users] Recent Install Docs?

[Alan Griffiths]

I believe that is the required setup - dedicated storage domain for HE.
It's certainly the case on 4.0, I haven't played with 4.1 yet.

For docs you can always check the RHV set, they are generally applicable to
oVirt.

[ovirt-users] Guest Agent Running unconfined on Centos 7

[Alan Griffiths]

Hi,

I'm running ovirt-guest-agent from Centos 7 EPEL and I notice that it's
running unconfined rather than within its own domain.

I see there is a rhev_agentd_exec_t type, which I attempted to assign to
ovirt-guest-agent.py but it still starts up as unconfined. Is there a
supported process for getting ovirt-guest into its own domain? Or a reason
why it's not possible?

Thanks,

Alan

[ovirt-users] Extend HE Disk

[Alan Griffiths]

Hi,

I can see it's possible to edit CPU and memory allocation of HE in the GUI,
but it doesn't seem possible to edit the disk. If I try I get a "VM not
managed by engine" error.

>From this post last year it implied that this feature was due in 3.6.

http://lists.ovirt.org/pipermail/users/2015-March/031783.html

Is there a method of doing this? I'm running 4.0.5.5-1.el7.centos

Thanks,

Alan
