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-host.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.

oVirt 4.3 DWH with Grafana
by Vrgotic, Marko
Dear oVirt,
We are currently running oVirt 4.3 and upgrade/migration to 4.4 won’t be possible for few more months.
I am looking into guidelines, how to, for setting up Grafana using DataWarehouse as data source.
Did anyone already did this, and would be willing to share the steps?
Kindly awaiting your reply.

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com
I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server.
I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template.
When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template.
It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue.
Has anyone else noticed this behavior? Is this expected or have I missed something?
Thanks for your input!

Restored engine backup: The provided authorization grant for the auth code has expired.
by Nicolás
Hi,
I'm restoring a full ovirt engine backup, having used the --scope=all
option, for oVirt 4.3.
I restored the backup on a fresh CentOS7 machine. The process went well,
but when trying to log into the restored authentication system I get the
following message which won't allow me to log in:
The provided authorization grant for the auth code has expired.
What does that mean and how can it be fixed?
Thanks.

Removing Direct Mapped LUNs
by Ryan Chewning
Hi List,
We need to add and remove directly mapped LUNs to multiple VMs in our
Non-Production environment. The environment is backed by an iSCSI SAN. In
testing when removing a directly mapped LUN it doesn't remove the
underlying multipath and devices. Several questions.
1) Is this the expected behavior?
2) Are we supposed to go to each KVM host and manually remove the
underlying multipath devices?
3) Is there a technical reason that oVirt doesn't do this as part of the
steps to removing the storage?
This is something that was handled by the manager in the previous
virtualization that we used, Oracle's Xen based Oracle VM.
Thanks!
Ryan

Libgfapi considerations
by Jayme
Are there currently any known issues with using libgfapi in the latest
stable version of ovirt in hci deployments? I have recently enabled it and
have noticed a significant (over 4x) increase in io performance on my vms.
I’m concerned however since it does not seem to be an ovirt default
setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?

Grafana oVirt 4.4.4 Node install - Grafana Monitoring Portal not available
by simon＠justconnect.ie
Having installed oVirt 4.4.4 HCI 3 node cluster, the Grafana 'Monitoring Portal' was not visible on the Default page.
It appears that Grafana is installed but not configured.
I have checked a 4.4.3 environment and it is installed and running, so is this a bug with 4.4.4.7-1.el8?
Any help would be appreciated.
