IPv6 Support
by David White
Hello,
Reading https://www.ovirt.org/documentation/administration_guide/index.ht..., I see this tidbit:
- Dual-stack addressing, IPv4andIPv6, is not supported
- Switching clusters from IPv4 to IPv6 is not supported.
If I'm understanding this correctly... does that mean I cannot run some VMs with IPv4, and other VMs with IPv6, in the same cluster?
If so, that's incredibly disappointing and frustrating.
Is Dual-stack addressing a possible feature request?
IPv4 addresses are expensive... and I have a couple of customers who only needs IPv6, so would really prefer to avoid having to pay for IPv4 addresses for them.

Question about Template and Storage Domain
by Nur Imam Febrianto
Hi,
Want to ask about template. For example I have a several template (with disk) stored in some Storage Domain. If I create a VM from the template, and when I change the parameter of cloned disk into another storage domain (different with where the template are stored). The VM always failed to be created. This only occurs in VM creation phase, if I create the VM at same storage domain where the templates are stored, it created successfully. Is this are “normal” behavior ?
Thanks before.

Right now oVirt is not supporting arm64. There was an initiative about
supporting it started some time ago from openEuler ovirt SIG.
I didn't got any further updates on this topic, looping in those who I
remember being looking into it.
I think that if someone contributes arm64 support it would also be a
feature worth a 4.5 release :-)

Mount Export Domain only temporary
by jb
Hello community,
We use a NFS export domain for full backups. Sometimes I have to restart
the NFS file server, but when I just restart that server, without doing
anything in oVirt (I guess normally I should put the domain in
maintenance mode), it can happen that hosts and VMs a crashing.
I had one time even the issue, that after a crash one XFS file system on
one host got damage and I had to fix that.
My though was now, because I make only one time a week a VM full backup,
I only mount the export domain in this time.
Is there an easy way to do this, with the API? Or would you have a other
hint, how to solve this issue?
Have a good day!

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

The oldest CPU is SandyBridge family (E5-2609)
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.
