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

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.

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 ???

How to renew vmconsole-proxy* certificates
by capelle＠labri.fr
Hi,
Since a few weeks, we are not able to connect to the vmconsole proxy:
$ ssh -t -p 2222 ovirt-vmconsole@ovirt
ovirt-vmconsole@ovirt: Permission denied (publickey).
Last successful login record: Mar 29 11:31:32
First login failure record: Mar 31 17:28:51
We tracked the issue to the following log in /var/log/ovirt-engine/engine.log:
ERROR [org.ovirt.engine.core.services.VMConsoleProxyServlet] (default task-11) [] Error validating ticket: : sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Indeed, certificate /etc/pki/ovirt-engine/certs/vmconsole-proxy-helper.cer and others did expire:
--
# grep 'Not After' /etc/pki/ovirt-engine/certs/vmconsole-proxy-*
/etc/pki/ovirt-engine/certs/vmconsole-proxy-helper.cer: Not After : Mar 31 13:18:44 2021 GMT

/etc/pki/ovirt-engine/certs/vmconsole-proxy-user.cer: Not After : Mar 31 13:18:44 2021 GMT

But we did not manage to found how to renew them. Any advice ?

Snapshot and disk size allocation
by jorgevisentini＠gmail.com
Hello everyone.
I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage.
I'm using the oVirt 4.3.10
How do I reprovision the VM disk?
Thank you all.

HA VM and vm leases usage with site failure
by Gianluca Cecchi
Hello,
supposing latest 4.4.7 environment installed with an external engine and
two hosts, one in one site and one in another site.
For storage I have one FC storage domain.
I try to simulate a sort of "site failure scenario" to see what kind of HA
I should expect.
The 2 hosts have power mgmt configured through fence_ipmilan.
I have 2 VMs, one configured as HA with lease on storage (Resume Behavior:
kill) and one not marked as HA.
Initially host1 is SPM and it is the host that runs the two VMs.
Fencing of host1 from host2 initially works ok. I can test also from
command line:
# fence_ipmilan -a 10.10.193.152 -P -l my_fence_user -A password -L
operator -S /usr/local/bin/pwd.sh -o status
Status: ON
On host2 I then prevent reaching host1 iDRAC:
firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -d 10.10.193.152 -p
udp --dport 623 -j DROP
firewall-cmd --direct --add-rule ipv4 filter OUTPUT 1 -j ACCEPT
so that:
# fence_ipmilan -a 10.10.193.152 -P -l my_fence_user -A password -L
operator -S /usr/local/bin/pwd.sh -o status
2021-08-05 15:06:07,254 ERROR: Failed: Unable to obtain correct plug status
or plug is not available
On host1 I generate panic:
# date ; echo 1 > /proc/sys/kernel/sysrq ; echo c > /proc/sysrq-trigger
Thu Aug 5 15:06:24 CEST 2021
host1 correctly completes its crash dump (kdump integration is enabled) and
reboots, but I stop it at grub prompt so that host1 is unreachable from
host2 point of view and also power fencing not determined
At this point I thought that VM lease functionality would have come in
place and host2 would be able to re-start the HA VM, as it is able to see
that the lease is not taken from the other host and so it can acquire the
lock itself....
Instead it goes through the attempt to power fence loop
I wait about 25 minutes without any effect but continuous attempts.
After 2 minutes host2 correctly becomes SPM and VMs are marked as unknown
At a certain point after the failures in power fencing host1, I see the
event:
Failed to power fence host host1. Please check the host status and it's
power management settings, and then manually reboot it and click "Confirm
Host Has Been Rebooted"
If I select host and choose "Confirm Host Has Been Rebooted", then the two
VMs are marked as down and the HA one is correctly booted by host2.
But this requires my manual intervention.
Is the behavior above the expected one or the use of VM leases should have
allowed host2 to bypass fencing inability and start the HA VM with lease?
Otherwise I don't understand the reason to have the lease itself at all....
Thanks,
Gianluca

Ooops! in last step of Hyperconverged deployment
by Harry O
Hi,
In the second engine dep run in Hyperconverged deployment I get red "Ooops!" in cockpit.
I think it fails on some networking setup.
The first oVirt Node says "Hosted Engine is up!" but the other nodes is not added to HostedEngine yet.
There is no network connectivity to the Engine outside node1, I can ssh to engine from node1 on the right IP-address.
Please tell what logs I should pull.

Sparse VMs from Templates - Storage issues
by Shantur Rathore
Hi all,
I have a setup as detailed below
- iSCSI Storage Domain
- Template with Thin QCOW2 disk
- Multiple VMs from Template with Thin disk
oVirt Node 4.4.4
When the VMs boots up it downloads some data to it and that leads to
increase in volume size.
I see that every few seconds the VM gets paused with
"VM X has been paused due to no Storage space error."
and then after few seconds
"VM X has recovered from paused back to up"
Sometimes after a many pause and recovery the VM dies with
"VM X is down with error. Exit message: Lost connection with qemu process."
and I have to restart the VMs.
My questions.
1. How to work around this dying VM?
2. Is there a way to use sparse disks without VM being paused again and
again?
Thanks in advance.
