Upgrade Host Compatibility Version
by jb
Hello everybody,
for some days I upgrade our environment from ovirt 4.3 to 4.4.2 and now
I stuck on upgrading the host compatibility version. It show there a
compatibility until version 4.4. The VMs have a limit until version 4.5
and the cluster shows to that I can upgrade them until 4.5.
On the cluster page is also a Upgrade guide, but this fails when I try
that one. At the moment I have only one host to upgrade (no hosted
engine)...
Thanks for helping!

oVirt 4.3.10 and ansible default timeouts
by Gianluca Cecchi
Hello,
in the past when I was in 4.3.7 I used this file:
/etc/ovirt-engine/engine.conf.d/99-ansible-playbook-timeout.conf
with
ANSIBLE_PLAYBOOK_EXEC_DEFAULT_TIMEOUT=80
to bypass the default of 30 minutes at that time.
I updated in steps to 4.3.8 (in February), 4.3.9 (in April) and 4.3.10 (in
July).
Due to an error on my side I noticed that the task for which I extended the
ansible timeout (this task I didn't execute anymore in latest months) fails
with timeout after 80 minutes indeed.
With the intent to extend again the custom timeout I went to
/usr/share/ovirt-engine/services/ovirt-engine/ovirt-engine.conf, provided
by ovirt-engine-backend-4.3.10.4-1.el7.noarch
and actually I see this inside:
"
# Specify the ansible-playbook command execution timeout in minutes. It's
used for any task, which executes
# AnsibleExecutor class. To change the value permanentaly create a conf
file 99-ansible-playbook-timeout.conf in
# /etc/ovirt-engine/engine.conf.d/
ANSIBLE_PLAYBOOK_EXEC_DEFAULT_TIMEOUT=120
"
and the file seems the original provided, not tampered:
[root@ovmgr1 test_backup]# rpm -qvV
ovirt-engine-backend-4.3.10.4-1.el7.noarch | grep virt-engine.conf$
......... /usr/share/ovirt-engine/services/ovirt-engine/ovirt-engine.conf
[root@ovmgr1 test_backup]#
So the question is: has the default intended value passed to 120 in 4.3.10
(or in any version after 4.3.7)?
Thanks,
Gianluca

CEPH - Opinions and ROI
by Jeremey Wise
I have for many years used gluster because..well. 3 nodes.. and so long as
I can pull a drive out.. I can get my data.. and with three copies.. I have
much higher chance of getting it.
Downsides to gluster: Slower (its my home..meh... and I have SSD to avoid
MTBF issues ) and with VDO.. and thin provisioning.. not had issue.
BUT.... gluster seems to be falling out of favor. Especially as I move
towards OCP.
So.. CEPH. I have one SSD in each of the three servers. so I have some
space to play.
I googled around.. and find no clean deployment notes and guides on CEPH +
oVirt.
Comments or ideas..

Is it possible to change scheduler optimization settings of cluster using ansible or some other automation way
by Kushagra Agarwal
I was hoping if i can get some help with the below oVirt scenario:
*Problem Statement*:-
Is it possible to change scheduler optimization settings of cluster using
ansible or some other automation way
*Description*:- Do we have any ansible module or any other CLI based
approach which can help us to change 'scheduler optimization' settings of
cluster in oVIrt. Scheduler optimization settings of cluster can be found
under Scheduling Policy tab ( Compute -> Clusters(select the cluster) ->
click on edit and then navigate to scheduling policy
Any help in this will be highly appreciated.
Thanks,
Kushagra

Hi oVIrt wizards,
One of my LocalStorage hypervisors dies. VMs do not need to be rescued.

What is the step or are steps to clean ovirt engine db from these VMs and its Storage/Hypervisor/Cluster/DC?

Kindly awaiting your reply.

If you can’t go direct, how about round about, with an iSCSI gateway.

[ANN] oVirt 4.4.3 Third Release Candidate is now available for testing
by Lev Veyde
oVirt 4.4.3 Third Release Candidate is now available for testing
The oVirt Project is pleased to announce the availability of oVirt 4.4.3
Third Release Candidate for testing, as of October 1st, 2020.
This update is the third in a series of stabilization updates to the 4.4
series.
How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1
Note: Upgrading from 4.4.2 GA should not require re-doing these steps, if
already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only
required to be done once.
Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> -
Host enter emergency mode after upgrading to latest build
If you have your root file system on a multipath device on your hosts you
should be aware that after upgrading from 4.4.1 to 4.4.3 you may get your
host entering emergency mode.
In order to prevent this be sure to upgrade oVirt Engine first, then on
your hosts:
1.
Remove the current lvm filter while still on 4.4.1, or in emergency mode
(if rebooted).
2.
Reboot.
3.
Upgrade to 4.4.3 (redeploy in case of already being on 4.4.3).
4.
Run vdsm-tool config-lvm-filter to confirm there is a new filter in
place.
5.
Only if not using oVirt Node:
- run "dracut --force --add multipath” to rebuild initramfs with the
correct filter configuration
6.
Reboot.

VM AutoStart
by Jeremey Wise
When I have to shut down cluster... ups runs out etc.. I need a sequence
set of just a small number of VMs to "autostart"
Normally I just use DNS FQND to connect to oVirt engine but as two of my
VMs are a DNS HA cluster.. as well as NTP / SMTP /DHCP etc... I need
those two infrastructure VMs to be auto boot.
I looked at HA settings for those VMs but it seems to be watching for pause
/resume.. but it does not imply or state auto start on clean first boot.
Options?
