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!

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.

It looks like engine sent:
parent_checkpoint_id: None
This issue was fix in engine few weeks ago.
Which engine and vdsm versions are you testing?

This is likely a result of the first error. If starting backup failed the
backup entity
is deleted.

by Nathanaël Blanchet
Hello, is there a way to poweroff or reboot (without stopped and running
state) a vm with the ovirt_vm ansible module?

oVirt 4.4.4 not dislaying Sign-on Screen
by louisb＠ameritech.net
I recently installed oVirt 4.4.4, everything appeared to run successfully, however, I’m unable to get the sign-on screen to display on my RHEL 8.3 machine. I did do an install using the remote database installation. I encountered no issue with the install, I can see the “engine” and “ovirt_engine_history” in PostgreSQL 13.3. The tables and table spaces have all been created as designed by the installation process.
When I enter the URL that was displayed once the installation completed I get the following information displayed on the screen:
Internal Error
I’ve tried using the port 443 and port 80 URL and get the same results. The URL are as follows:
http://WorkstationName:80/ovirt-engine
https://WorkstationName:443/ovirt-engine
For three days I’ve been trying to locate logs that will help me located and resolve the problem, but so far I’ve had no luck.
Can anyone tell where I should start looking to resolve my issue? I’ve checked several system logs and logs for Apache with luck. What should I be looking for within the logs? What logs should I be looking at?
I don’t believe my issue is with the back-end database, I thinks its something with Apache not being able to find the web pages to display. How can I start to investigate my problem an develop a solution?
My Linux/RHEL 8.3 OS has all of the latest patches and fixes applied.
Thanks

Problems after upgrade from 4.4.3 to 4.4.4
by tferic＠swissonline.ch
Hi
I have problems after upgrading my 2-node cluster from 4.4.3 to 4.4.4.
Initially, I performed the upgrade of the oVirt hosts using the oVirt GUI (I wasn't planning any changes).
It appears that the upgrade broke the system.
On host1, the ovirt-engine was configured to run on the oVirt host itself (not self-hosted engine).
After the upgrade, the oVirt GUI didn't load in the Browser anymore.
I tried to fix the issue by migrating to self-hosted engine, which did not work, so I ran engine restore and engine-setup in order to get back to the initial state.
I am now able to login to the oVirt GUI again, but I am having the following problems:
host1 is in status "Unassigned", and it has the SPM role. It cannot be set to maintenance mode, nor re-installed from GUI, but I am able to reboot the host from oVirt.
All Storage Domains are inactive. (all NFS)
In the /var/log/messages log, I can see the following message appearing frequently: "vdsm[5935]: ERROR ssl handshake: socket error, address: ::ffff:192.168.100.61"
The cluster is down and no VM's can be run. I don't know how to fix either of the issues.
Does anyone have an idea?
I am appending a tar file containing log files to this email.

Locked disks
by Giulio Casella
Since yesterday I found a couple VMs with locked disk. I don't know the
reason, I suspect some interaction made by our backup system (vprotect,
snapshot based), despite it's working for more than a year.
I'd give a chance to unlock_entity.sh script, but it reports:
CAUTION, this operation may lead to data corruption and should be used
with care. Please contact support prior to running this command
Do you think I should trust? Is it safe? VMs are in production...
My manager is 4.4.4.7-1.el8 (CentOS stream 8), hosts are oVirt Node 4.4.4
TIA,
Giulio
