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!

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?

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.

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

supervdsm failing during network_caps
by Alan G
Hi,
I have issues with one host where supervdsm is failing in network_caps.
I see the following trace in the log.
MainProcess|jsonrpc/1::ERROR::2020-01-06 03:01:05,558::supervdsm_server::100::SuperVdsm.ServerCallback::(wrapper) Error in network_caps

IOError: [Errno 16] Message sequence number mismatch
A restart of supervdsm will resolve the issue for a period, maybe 24 hours, then it will occur again. So I'm thinking it's resource exhaustion or a leak of some kind?
Running 4.2.8.2 with VDSM at 4.20.46.
I've had a look through the bugzilla and can't find an exact match, closest was this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be a RHV only fix.
Thanks,
Alan

The he_fqdn proposed for the engine VM resolves on this host - error?
by lejeczek
hi chaps,
a newcomer here. I use cockpit to deploy hosted engine and I
get this error/warning message:
"The he_fqdn proposed for the engine VM resolves on this host"
I should mention that if I remove the IP to which FQDN
resolves off that iface(plain eth no vlans) then I get this:
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false,
"msg": "The selected network interface is not valid"}
All these errors seem bit too cryptic to me.
Could you shed bit light on what is oVirt saying exactly and
why it's not happy that way?
many thanks, L.

Upgrade from 4.4.3 to 4.4.4 (oVirt Node) - vdsmd.service/start failed with result 'dependency'
by Marco Fais
Hi all,
I have just upgraded one of my oVirt nodes from 4.4.3 to 4.4.4.
After the reboot, the 4.4.4 image is correctly loaded but vdsmd is not
starting due to this error:
vdsmd.service: Job vdsmd.service/start failed with result 'dependency'.
Looks like it has a dependency on mom-vdsm, and this as well has a
dependency issue:
mom-vdsm.service: Job mom-vdsm.service/start failed with result
'dependency'.
After some investigation looks like mom-vdsm has a dependency
on ovsdb-server, and this is the unit creating the problem:
ovs-delete-transient-ports.service: Starting requested but asserts failed.
Assertion failed for Open vSwitch Delete Transient Ports
Failed to start Open vSwitch Database Unit.
Details below:
