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.

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.

How to assign a server disk and nic profile via REST API?
by ovirt.org＠nevim.eu
Hello to everybody,
for about an hour I have stuck my nose in the ovirt and rhev documentation, but I still can't understand how to use the REST API to change the disk profile and nothing the server profile.
Ideally, how to set it for them when setting up a VM.
Thank you so much for the advice.
