Re: oVirt 4.2 how to upgrade
by Strahil Nikolov
Theoretically you most probably can, but you take the risk of being vulnerable to split-brain.
Keep in mind that you can:- update gluster to the same version that is used on oVirt 4.4- update oVirt to 4.3.10 as this is the most tested migration scenario- reduce the volume and remove that 3rd node (don't forget to peer detach)- reinstall with EL8 and install gluster (same version) again. Add the brick and qait for the heal- create a new volume for the new HE- Stop the old HE and deploy the new one from the backup- Add the hosts to the new HE and migrate some of the VMs to free one of the old hosts- Reinstall the remaining hosts (one by one) to EL8

and incidentally it has connectivity problems with IPMI NIC,
but Hosted Engine HA is enabled and working.
May I reduce the glusterfs replica to 2 and use one of the 3 nodes to begin the installation of ovirt 4.4 on that node?

[ANN] oVirt 4.4.7 Fifth Release Candidate is now available for testing
by Lev Veyde
oVirt 4.4.7 Fifth Release Candidate is now available for testing
The oVirt Project is pleased to announce the availability of oVirt 4.4.7
Fifth Release Candidate for testing, as of June 24th, 2021.
This update is the seventh 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 or later 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 4.4.7 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 4.4.7 (redeploy in case of already being on 4.4.7).
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.

Expected behavior when link of required VM networks down
by Gianluca Cecchi
Hello,
suppose I have a cluster with required VM logical network setup.
Suppose on hosts I have configured a bonding device with this logical
network mapped on it.
Suppose an active host for any reason loses the physical connectivity on
this bond (both links down or problems with new network config impacting
the bond, ecc)
So from the VMs point of view, those having a vnic on this logical network
will lose the connectivity, but I think they will not detect link down,
correct?
Is there any expected default action oVirt will take in respect of this
scenario or not?
Of course I expect to see events with messages about link down. But any
automatic action such as live migration of impacted VMs for example?
Any configurable one at oVirt level?
Thanks,
Gianluca

oVirt 4.4.5 - Windows Server 2003 VM Reboot problems
by simon＠justconnect.ie
Hi All,
I've had to migrate a Windows Server 2003 R2 VM from VMWare to oVirt which I have successfully managed to get running.
The problem I have is if I try to reboot from the OS I receive the following message after the VM shuts down but doesn't reboot:
"Exit message: Lost connection with qemu process."
Also any attempt to either shutdown or reboot from oVirt Manager has no effect.
I realize that this OS is not supported in the current oVirt version, but is there something I am missing to get it working 'unsupported' please?
Regards
Simon...
