Thanks for the clarification. I don't have
/usr/share/ovirt-engine/ansible-runner/artifacts on my engine machine.
Which version do you use? Perhaps file a bug in bugzilla and attach a
sosreport.

What do you mean by that? Did you try changing it and saw that this
does not affect it at all? Or a specific setting? Something else?

Thanks and best regards,

[ovirt-users] Deploying ovirt+gluster hyperconverged with standalone engine

[J W]

I'm looking for the proper steps to deploy ovirt+gluster hyperconverged with 
standalone engine as the scenario doesn't seem to be covered here: 
https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying_Hyperconverged.html

I have attempted to:
1) Deploy standalone engine
2) deploy 3 nodes and ran gluster deployment, stopping before the engine deploy
3) Added hosts to standalone engine

I then attempt to add the gluster volumes to the standalone engine by 
specifying host1:/volume as glusterfs but the volume does not successfully add.

Is there another perferred method for this type of deployment?

[ovirt-users] Re: fresh hyperconverged Gluster setup failed in ovirt 4.4.8

[Eddie Garcia]

I have been having this issue as well with no solution working but I came
across something interesting. In selinux-policy 3.14.3-77 they removed the
glusterd selinux module.

https://centos.pkgs.org/8-stream/centos-baseos-x86_64/selinux-policy-3.14.3-78.el8.noarch.rpm.html

so that policy doesn exist anymore for ansible to apply. I plan on testing
installing an older version into an ovirt node box to test which defaults
as of 4.4.8 to selinux-policy version 3.14.3-79.el8.

A clean install of CentOS 8 using latest iso has version 3.14.3-67.el8_4.2
and I can verify that manually setting policy with command 'semanage
fcontext -a -t glusterd_brick_t "/gluster_bricks(/.*)?"' is completed
successfully.

[ovirt-users] Re: qemu-guest-agent not reporting IP address on boot?

[Schreuders, Cliffe]

Thank you. It does look like that bug could be related.

I had an earlier version of the VM template which continued to work correctly, 
and an updated version (via apt-get dist-upgrade) that did not report IP 
addresses correctly.

I suspected that it might be related to the new ovirt/qemu user agent, so I 
hold/pinned "ovirt-guest-agent" on the older template before re-running the 
software updates.

This worked to create an updated Kali VM that reports it's IP address (albeit 
more-or-less stuck with whatever dependencies the last ovirt-guest-agent has) 
so it seems this is indeed an issue with qemu-guest-agent vs ovirt-guest-agent.

Cheers,
Cliffe.

Hi folks,

Kali Linux repos (based on Debian) no longer ship ovirt-guest-agent, and 
instead package qemu-guest-agent. However, since this upgrade VMs based on Kali 
no longer report their IP address to oVirt (and therefore timeout during 
provisioning). If I interact with the VM console, the VM does have an IP 
address, and the agent is running, yet oVirt reports N/A IP address. I've tried 
restarting the agent, but that does not help. If I load the console and use the 
VM it seems to increase the chances the IP address will eventually makes it's 
way to oVirt, although I can't seem to reproduce an update, or get it to 
provide the IP address on boot so that provisioning works reliably.

Any suggestions would be really appreciated.

Might be the same as/related to 
https://bugzilla.redhat.com/show_bug.cgi?id=1981946
 which is still being investigated


Thank you.

[ovirt-users] Import ISCSI target as data domain, cannot see old data

[joyzhao93]

Hi Team,
Hope you are doing well.

I had a standalone Ovirt Engine with 2 hosts, one 2TB ISCSI data domain (dell 
equallogic). Today the Ovirt Engine machine crashed so we have to bring up a 
new one, setup is good and when I try to import ISCSI data domain I can see 
volumes/Luns, but after import, Ovirt shows the volume is empty - 2TB free (so 
all old data on the ISCSI volume is not presenting). However when I login to 
the ISCSI target machine, it shows the old data (around 400GB) is in use.  
Seems like the new Ovirt Engine cannot detect the old ISCSI data domain disk 
content.

Thank you,
Sincerely,
SYZhao

[ovirt-users] Engine backup / restore

[duparchy]

Hi, 

I'm testing Backup / Restore of the engine.

Once the engine is restored ; how to resync the engine database with the 
"reality" of the Storage Domains ? (I'm talking about  anything that could have 
been done after the engine backup : Deleted / Created VMs ; Snapshots taken 
since the backup, etc.. 

I'm on 4.3, Oracle LVM context.

 My Tests : 

- Create a snapshot of some random VM. Say VM-1
- Enable that VM preview and start it on a host.

- Stop OLVM engine server.
- Start a full backup copy of that OLVM engine (That backup being a snapshot 
taken, say, yesterday. Our test OLVM engine being a VM running in another 
separate virltualization infrastucture.)

The restored OLVM does not show the existence of the VM-1 snapshot. It only 
shows the VM running on the active instance. No snapshot.
I tried Storage Domain / Scan disks. No refresh to be seen.

[ovirt-users] Re: Hosted Engine ansible runner artifacts cleanup

[Erez Zarum]

Hey,
No, i am talking about the ansible-runner artifacts, when the ovirt-engine runs 
a playbook (which is a task in the webui for example), it creates a folder in 
/usr/share/ovirt-engine/ansible-runner/artifacts for each run.

There's a config.yml in /etc/ansible-runner-service but for some reason it does 
not affect anything.

Thanks.

[ovirt-users] Re: Hosted Engine ansible runner artifacts cleanup

[Martin Necas]

Hi,

if you are talking about the
`/var/log/ovirt-engine/ansible-runner-service.log`.
The logrotate is located in `/etc/logrotate.d/ansible-runner-service` and
should archive weekly.
Should work automatically from ansible-runner-service 1.0.7.

The logroate includes daily the `/etc/logrotate.d` in
`/etc/cron.daily/logrotate` so it should be loaded.
It is possible that you have broken the logrotate/cron.

I think the only thing out-of-the-box that should clean these logs is
logrotate, for which we indeed supply a conf file.
Does logrotate run on your system? Should run daily by default, by cron.

The configuration was changed recently, see also:

[Erez Zarum]

Hey,
the ovirt-engine runs ansible playbooks and uses the ansible-runner project, 
what happens is that if you have a lot of tasks the artifacts of ansible-runner 
fills up the disk space of the ovirt-engine.
They are located in /usr/share/ovirt-engine/ansible-runner
There's a config in /etc/ansible-runner-service that controls the artifacts 
rotation, for some reason it does not kick in, in general there's a way to 
manually run the ansible-runner and let it rotate the artifacts, i want to 
understand how to do this without messing up the ovirt-engine.

not sure what you mean by "KVM/libvirt storage domain", but what matters is 
what's inside OVA file which you specify on line 63 (https://github.com/oVirt/
python-ovirt-engine-sdk4/blob/main/examples/import_vm_from_ova.py#L63). 

See Arik's answer for more detail explanation. (maybe we should add it direcly 
into example?)

[ovirt . org]

https://ovirt.mydomains/ovirt-engine/apidoc/#/ is not working (page is blank, 
has ovirt horizontal menu, but content is empty).

You may mean the page 
https://ovirt.mydomains/ovirt-engine/apidoc/#/services/disk/methods/update

It works for me, but the information I see on it seems insufficient (unusable) 
to me:

update

This operation updates the disk with the appropriate parameters. The only field 
that can be updated is qcow_version.

For example, disk update can be done using the following request:

PUT /ovirt-engine/api/disks/123

With a request body like this:


  qcow2_v3


Since the backend operation is asynchronous, the disk element that is returned 
to the user might not be synced with the changed properties.

I have HTTP Error 400: Bad Request  Request syntactically incorrect. But syntax 
is OK:
