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

Dec 16 10:13:11 host01.ovn.di.unimi.it libvirtd[5667]: internal error:

2021-12-16T10:13:11.158057Z qemu-kvm: Failed to load pckbd:kbd

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,

Deploy ovirt-csi in the kubernetes cluster
by ssarang520＠gmail.com
Hi,
I want to deploy ovirt-csi in the kubernetes cluster. But the guide only has how to deploy to openshift.
How can I deploy the ovirt-csi in the kubernetes cluster? Is there any way to do that?

Host needs to be reinstalled after configuring power management
by Andrew DeMaria
Hi,
I am running ovirt 4.3 and have found the following action item immediately
after configuring power management for a host:
Host needs to be reinstalled as important configuration changes were
applied on it.
The thing is - I've just freshly installed this host and it seems strange
that I need to reinstall it.
Is there a better way to install a host and configure power management
without having to reinstall it after?
Thanks,
Andrew

Cinderlib RBD ceph template issues
by Sketch
This is on oVirt 4.4.8, engine on CS8, hosts on C8, cluster and DC are
both set to 4.6.
With a newly configured cinderlib/ceph RBD setup. I can create new VM
images, and copy existing VM images, but I can't copy existing template
images to RBD. When I do, I try, I get this error in cinderlib.log (see
below), which sounds like the disk already exists there, but it definitely
does not. This leaves me unable to create new VMs on RBD, only migrate
existing VM disks.

Import an exported VM using Ansible
by paolo＠airaldi.it
Hello everybody!
I'm trying to automate a copy of a VM from one Datacenter to another using an Ansible.playbook.
I'm able to:
- Create a snapshot of the source VM
- create a clone from the snapshot
- remove the snapshot
- attach an Export Domain
- export the clone to the Export Domain
- remove the clone
- detach the Export domain from the source Datacenter and attach to the destination.
Unfortunately I cannot find a module to:
- import the VM from the Export Domain
- delete the VM image from the Export Domain.
Any hint on how to do that?
Thanks in advance. Cheers.
Paolo
PS: if someone is interested I can share the playbook.

give cloud-init the VM name
by Luca Contessa
Hi list,
I have an oVirt node 4.4.9 installation with hyperconverged structure, on which i've created a pool of Linux VM (CentOS Stream 8).
I would like set as hostname the name of the VM + a static suffix appended at the end of the name (EXAMPLE: <VM name>.static.suffix ), is there a way to pass to cloud-init the name of the VM and do this via cloud-init?
I've tried to look for something in oVirt and cloud-init documentation and found nothing.
Thanks a lot to everybody for the help and have a nice day.

did 4.3.9 reset bug https://bugzilla.redhat.com/show_bug.cgi?id=1590266
by kelley bryan
I am experiencing the error message in the ovirt-hosted-engine-setup-ansible-create_target_vm log
{2020-05-06 14:15:30,024-0500 ERROR ansible failed {'status': 'FAILED', 'ansible_type': 'task', 'ansible_task': u"Fail if Engine IP is different from engine's he_fqdn resolved IP", 'ansible_result': u'type: <type \'dict\'>\nstr: {\'msg\': u"Engine VM IP address is while the engine\'s he_fqdn ovirt1-engine.kelleykars.org resolves to 192.168.122.2.

The bug 1590266 says it should report the engine VM IP address xxx.xxx.xxx.xxx while the Engines he_fqdn is xxxxxxxxx
I need to see what it thins is wrong as both dig fqdn engine name and dig -x ip return the correct information.
Now this bug looks like it may play but I don't see the failed rediness check in the this log https://access.redhat.com/solutions/4462431
or is it because the vm fails or dies or ???

Help installing oVirt on single machine, without cockpit
by Cameronsplaze222＠gmail.com
I'm trying to install both the oVirt engine (so I have the API), and hypervisor on the same machine. I'm hoping I don't need cockpit, and I can write some custom scripts to manage oVirt through the API. I tried a couple ways, and both were blocked:
# on CentOS 9 stream, installing oVirt engine:
On a fresh CentOS install, tried following the directions [here](https://www.ovirt.org/documentation/installing_ovirt_as_a_standalon.... They failed at step 3.2, when adding the modules (missing groups or modules). Tried skipping it, but step 3.3.2 failed when running `dnf install ovirt-engine`, package couldn't be found. The closest package I see is `ovirt-hosted-engine-setup-2.5.4-1.el9.noarch`. Is that what I want?
# On oVirt node, installing engine:
Couldn't get the networking working, even though I added it during the install process. Also tried wired connection, and no luck. Blocked early on, but read this was SUPER minimal anyway, so maybe this wasn't the right path.
I'm just trying to have a working API, along side the hypervisor to run vm's, both on the same machine. I'm down to go a third way too, if anyone has any ideas. Thanks!

After upgrade to vdsm-4.40.90.4-1.el8 - Internal JSON-RPC error - how to fix?
by John Mortensen
Hi,
After we upgraded to vdsm-4.40.90.4-1.el8 on our two node cluster two things has happned:
1. First node that was upgraded now continuously logs this error:
VDSM <node name> command Get Host Statistics failed: Internal JSON-RPC error: {'reason': "'str' object has no attribute 'decode'"}
2. During import of two virtual machines from VMware (has done multible before upgrade) the import seems to never finish - currently running on day 2-3... any clues how to fix this?

Unrecoverable NMI error on HP Gen8 hosts.
by Diggy Mc
I have oVirt Node v4.4.8.3 running on several HP ProLiant Gen8 servers. I receive the following error under certain circumstances:
"An Unrecoverable System Error (NMI) has occurred (iLO application watchdog timeout NMI, Service Information: 0x0000002B, 0x00000000)"
When a host starts taking a load (but nowhere near a threshold), I encounter the above iLO-logged error and the host locks-up. I have had to grossly under-utilize my hosts to avoid this problem. I'm hoping for a better fix or work-around.
I've had the same problem beginning with my oVirt 4.3.x hosts, so it isn't oVirt version specific.
The little information I could find on the error wasn't helpful. Red Hat acknowledges the issue, but limited to shutdown/reboot operations; not during "normal" operations.
Anyone else experienced this problem? How did you fix it or work around it? I'd like to better utilize my servers if possible.
In advance, thank you to anyone and everyone who offers help.
