How I'd like to contribute
by Glen Jarvis
I am researching how to contribute to the oVirt community. I started here:
https://www.ovirt.org/community/
And, I immediately saw to sign up for this email address and...send us an email saying how you would like to contribute. Visit our[mailing lists](https://lists.ovirt.org/archives/)page for other oVirt mailing lists to sign up for.
My answers are: I want to be useful (and give more than I take). I can answer questions on mailing lists, help troubleshoot, write ovirt.ovirt Ansible collections, roles and custom modules. I am a seasoned Python programmer.
My background:
- Python programmer for 10+ years
- I write custom Ansible modules, roles, playbook, etc.
- Previous DBA for Informix (highly certified but who has heard of informix anymore). Postgres and Informix are cousins (both offspring from Ingres)
- I have *some* rudimentary knowledge of Virtualization. However, I'm far from an expert
- One of my favorite OS's is Qubes (an OS of virtual machines really)
- I do a lot of technical training (writing materials and facilitating classes)
- I work in an SRE / SysAd role at a large company that puts music in peoples ears (I'm hoping to move some of this from less SysAd and more SRE when with some of this oVirt stuff we're working on).
My intermediate skills
- I have bought a book on libvirt. But, it's still on my backlog. It feels that I'm always sucking an ocean through a straw so I have to pick and choose what I read next
- My second favorite OS is Ubuntu as my main desktop (Qubes on separate computer for more secure stuff -- like crypto)
- I'm just starting to use Virtual Machine Manager to run other OSs on Ubuntu
My Oh-I-have-No-Idea skills:
- things like luns, iSCSI and the `vdsm-tool config-lvm-filter` are making me pull my hair out. This is the reason I was frustrated enough to say "Let me join this community so I can learn more how this architecture works."
- I work for a large company that has a RedHat support contract. We use RHV. I just wrote up this long descriptive case of the problem, uploaded sosreports, added as much detail as I could. But, it's crickets. If I knew more I could debug what was happening more myself.
How did I do for an introduction?
Cheers,
Glen Jarvis

Unable to migrate VMs to a newly upgraded Ovirt node host
by Giulio Casella
Hi guys,
I just faced a problem after updating a host. I cannot migrate VM to
updated host.
Here's the error I see trying to migrate a VM to that host.
Dec 16 10:13:11 host01.ovn.di.unimi.it systemd[1]: Starting Network
Manager Script Dispatcher Service...
Dec 16 10:13:11 host01.ovn.di.unimi.it libvirtd[5667]: Unable to read
from monitor: Connection reset by peer
Dec 16 10:13:11 host01.ovn.di.unimi.it libvirtd[5667]: internal error:
qemu unexpectedly closed the monitor: 2021-12-16T10:13:00.447480Z
qemu-kvm: -numa node,nodeid=0,cpus=0-15,mem=8192: warning: Parameter

2021-12-16T10:13:11.158057Z qemu-kvm: Failed to load pckbd:kbd
2021-12-16T10:13:11.158114Z qemu-kvm: error while loading state for

file or directory
Dec 16 10:13:11 host01.ovn.xx.xxxxx.it kvm[35663]: 0 guests now active
Instead I can start VM on that host, and migrate away VM from that host.
Rolling back to ovirt-node-ng-4.4.9.1-0.20211207.0+1 via host console
restores full functionality.
The affected version is ovirt-node-ng-4.4.9.3-0.20211215.0+1 (and also
previous one, I don't remember precisely, it was another async release).
Any ideas?
TIA,

This didn't work for me either, though it may have had to do with the many
issues I had moving from 4.3 to 4.4. What did work was backing up and
restoring to a standalone engine.
I had initially planned to migrate it back to a self-hosted setup later,
but found that this setup is a lot less temperamental than the self-hosted
engine. It also doesn't have to be a dedicated machine, it can be a VM
hosted outside of oVirt, which may also be useful if you're hosting some
stuff needed for bootstrapping the environment like DNS, NTP, etc. outside
of oVirt.

Note about oVirt and Let's Encrypt SSL certs
by Chris Adams
I was setting up a new oVirt cluster yesterday, and deployed a Let's
Encrypt SSL cert on it for the website. After that, I noticed that
oVirt was getting errors synchronizing networks with ovirt-provider-ovn.
It appears that the python library used for SSL by ovirt-provider-ovn
has the same issue as older OpenSSL versions, and can't handle the
default Let's Encrypt root cert path; the path used for old Android
compatibility can end with an expired cert that's still in the CA store
(even though there's another verification path that doesn't end with an
expired cert).
The solution was to switch the Let's Encrypt cert to the "ISRG Root X1"
chain (which is fine, since I don't log in to oVirt from Android 7
devices).
Just an FYI for anyone else using a Let's Encrypt cert (or other cert
with a similar expired root path, they aren't the only one).

[Call to Action] oVirt 4.5 localization updated in zanata
by Sandro Bonazzola
Hi, https://zanata.ovirt.org/ has been updated with new text to be translated.
If you want to help with this, please follow
https://ovirt.org/develop/localization.html
The ovirt-web-ui and ovirt-engine-ui-extensions projects lack Italian,
Czech and Turkish translation.
The oVirt engine project needs some touch on all the translations but
especially on Italian, Czech, Russian and Turkish
Thanks,
--

Migrate Hosted-Engine from one NFS mount to another NFS mount
by Brian Ismay
Hello,
I am currently running Ovirt 4.2.5.3-1.el7 with an Hosted-Engine running on
nfs-based storage.
I am needing to migrate the backend NFS store for the Hosted-Engine to a
new share.
Is there specific documentation for this procedure? I see multiple
references to a general procedure involving backing-up the existing install
and then re-installing and restoring the backup. Is there any way to make a
more clean change of the configuration?
Thanks,
Brian Ismay
