The breakage happened due to:
- ansible-core recently moved to python 3.9
- oVirt needs several python libraries in its use of ansible, some of
which are packaged by oVirt. Those are not yet built for python 3.9.

For the time being, try to downgrade ansible-core to 2.12, or the last
version requiring python 3.8.
We merged this patch to the engine master branch (to eventually become 4.5.3):
https://github.com/oVirt/ovirt-engine/pull/654
Going forward:
1. We hope to finish porting the engine to CS9 soon, and if this
proves stable, consider dropping support for CS8.
2. We might try, in the time being, to build the missing dependencies
for python 3.9. It's not clear if it's worth the effort.

You might want to reinstall them from scratch, one-by-one, if you care that much about them being clean. I personally do not think it's worth it if your only reason is getting rid of hosted-engine remains, but you might want to do this regardless for other reasons (e.g. if they are old machines and accumulated other kinds of cruft). > I noticed that the "hosted-engine" command still exists. I went to run a yum > remove on that, and it tried to remove basically everything... You can try 'dnf remove --noautoremove ovirt-hosted-engine-setup ovirt-hosted-engine-ha'. This will remove also 'ovirt-host', which is not such a good idea - it's a package that has no content, other than a list of dependencies, on the various packages needed for a functional oVirt host. Nothing will be broken immediately, but in principle you risk losing new deps added to a future version of it, etc. > so I figured that wasn't actually a good idea. > > Do I need to do anything in the oVirt config (maybe something in the Postgres > database) to basically tell it that it is no longer self-hosted, but is > instead stand-alone? I do not know all the details, sorry. You might want to deploy a hosted-engine, dump the engine db, then search the dump for 'hosted' or something like that. Even checking a dump of a standalone engine can show you relevant stuff to check. One item I do know about is how to prevent 'engine-setup' from preventing you from continuing because it thinks it's a hosted-engine and not in global maintenance: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/SKGWY5ZIBAG5GTWHIPDUO5O64PUZN7Y2/ There is also the field 'hosted_engine_configured' in 'vds_dynamic', not sure it's safe to change it outside of the engine (but no idea why it might not be).

[ovirt-users] Unable to deploy to new host
I currently have a self-hosted engine that was restored from a backup of an
engine that was originally in a hyperconverged state. (See
https://lists.ovirt.org/archives/list/users@ovirt.org/message/APQ3XBUM34TG76XGRBV6GIW62RP6MZOD/).
This was also an upgrade from ovirt 4.4 to ovirt 4.5.
There were 4 hosts in this cluster. Unfortunately, 2 of them are completely in
an "Unassigned" state right now, and I don't know why. The VMs on those hosts
are working fine, but I have no way to move the VMs or manage them.
More to the point of this email:
I'm trying to re-deploy onto a 3rd host. I did a fresh install of Rocky Linux
8, and followed the instructions at https://ovirt.org/download/ and at
https://ovirt.org/download/install_on_rhel.html, including the part there that
is specific to Rocky.
After installing the centos-release-ovirt45 package, I then logged into the
oVirt engine web UI, and went to Compute -> Hosts -> New, and have tried (and
failed) many times to install / deploy to this new host.
The last error in the host deploy log is the following:

On the engine, I have verified that netaddr is installed. And just for kicks,
I've installed as many different versions as I can find:
[root@ovirt-engine1 host-deploy]# rpm -qa | grep
netaddrpython38-netaddr-0.7.19-8.1.1.el8.noarch
python2-netaddr-0.7.19-8.1.1.el8.noarch
python3-netaddr-0.7.19-8.1.1.el8.noarch
The engine is based on CentOS Stream 8 (when I moved the engine out of the
hyperconverged environment, my goal was to keep things as close to the original
environment as possible)
[root@ovirt-engine1 host-deploy]# cat /etc/redhat-release
CentOS Stream release 8
The engine is fully up-to-date:
[root@ovirt-engine1 host-deploy]# uname -a
Linux ovirt-engine1.mgt.barredowlweb.com 4.18.0-408.el8.x86_64 #1 SMP Mon Jul
18 17:42:52 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
And the engine has the following repos:
[root@ovirt-engine1 host-deploy]# yum repolistrepo id

[ovirt-users] Re: Gluster setup for oVirt
It's not outdated but it's rarely necessary because:- the HostedEngine volume must be dedicated for the HE VM. Setting enough space for the bricks is enough - for example physical disk is 100GB, Thinpool is 100GB, thin LV 84GB (16GB should be put aside for the metadata). In such configuration, you can't go out of space.I/O overhead can be minimized by setting the full stripe size (and the thinpool chunk size) between 1MiB and 2MiB (preferably in the lower end). One big advantage of the thinpool-based bricks is that you can create snapshots of the volume. Usually I shut down the engine, snapshot the volume and then power up and do the necessary actions (for example Engine upgrade).

[ovirt-users] Re: VMs hang periodically: gluster problem?
I hope you do realize that modern consumer SSDs have a small cache (at least according to https://www.storagereview.com/review/samsung-860-evo-ssd-review ) and we can't rule out the disks. Use gluster's top command to view the read (17.2.6) and write (17.2.7) performance of the bricks before (regular usage), during (high load) and after the backup (regular usage): https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/sect-running_the_volume_top_command Best Regards,Strahil Nikolov On Sat, Sep 17, 2022 at 17:49, Diego Ercolani wrote: Parameter cluster.choose-local set to off.

[ovirt-users] Re: Migrating VM from old ovirt to a new one
Stop the Storage domains in oVirt and attach the same Gluster volumes on the new cluster.Then Import the templates and the VMs from the new engine. Keep in mind that you might need to delete all VMs' snapshots and if needed to import the same VM as many times as the number of disks those VMs have. I would give a try to this one as theoretically might work:- revert the time on all hosts- block NTP- power on the engine. Then you can try to regenerate all certs and shutdown again to fix the time.

[ovirt-users] oVirt 4.5 on Rocky 9
Hi, I'm moving all my infra nodes to Rocky 9 and my oVirt cluster is next on the list. I'm deploying a standalone oVirt VM on a KVM box and will set up the hosts afterwards. All are to run on Rocky 9 x86_64. I followed https://www.ovirt.org/download/install_on_rhel.html and created an Ansible playbook to set up the customisations. I now have all repos set up correctly, or at least that is my understanding. When I run yum search ovirt-engine I get a number of packages available from the repos, but not the ovirt-engine package. I do see the ovirt-hosted-engine, but I prefer the standalone option. This makes sense as I don't find the package at http://mirror.stream.centos.org/SIGs/9-stream/virt/x86_64/ovirt-45/Packages/o/ , which I where all ovirt- packages are, except this one. Yum whatprovides engine-setup also turns out negative. I then decided to install ovirt-engine-appliance 4.5-20220419160254.1.el9 from ovirt-45-upstream, but that package produces an error on the GPG key import. It's unclear whether the issue is on my specific stack or wider. The missing ovirt-engine package is confusing though.

[ovirt-users] Re: Error during deployment of ovirt-engine
Hi Jonas, I get the same error when I try to install. Last weekend I managed to do it (but with a lot of other problems) so something has changed during the week. After the VM is up I logged in through ssh and saw that the oVirt appliance comes with Python-3.6 and Python-3.8 which both have netaddr installed. Part of the log: ... [ INFO ] TASK [ovirt.ovirt.engine_setup : Update setup packages] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.engine_setup : Copy yum configuration file] [ INFO ] changed: [localhost -> 192.168.222.35] [ INFO ] TASK [ovirt.ovirt.engine_setup : Set 'best' to false] [ INFO ] changed: [localhost -> 192.168.222.35] [ INFO ] TASK [ovirt.ovirt.engine_setup : Update all packages] [ INFO ] changed: [localhost -> 192.168.222.35] [ INFO ] TASK [ovirt.ovirt.engine_setup : Remove temporary yum configuration file] [ INFO ] changed: [localhost -> 192.168.222.35] [ INFO ] TASK [ovirt.ovirt.engine_setup : Set offline parameter if variable is set] ... I noticed that after the task "Update all packages" Python-3.9 gets installed and that version does not have netaddr installed. My theory is that the playbook somehow uses the newest version of Python which is installed. pip3.9 list Package Version --- ansible-core 2.13.3 cffi 1.14.3 cryptography 3.3.1 idna 2.10 pip 20.2.4 ply 3.11 pycparser2.20 PyYAML 5.4.1 setuptools 50.3.2 six 1.15.0 I have tried another run where I installed the netaddr module as soon as Python-3.9 got installed and that installation went further but then it had another error. When I log into my hosted engine VM from last week there is no Python-3.9. My dnf(1) skills are not good enough to figure out which dependency is causing Python-3.9 to be installed. There are probably a lot of other modules missing that can explain the other error(s) I see. I will see if I can find out how to file a proper bug report.
