Hi..
I'm looking to migrate soon from CentOS 7.9 with oVirt 4.3.10 to Rocky
Linux 8.4 with oVirt 4.4.6. I'm working on my kickstart of my
standalone engine in a VM at the moment.
So far, with minimal experience with Rocky Linux, after my kickstart, I
was able to run "engine-setup", follow all the defaults and then access
my "new" engine via web. I have to explore the actual procedure for
installing on my current engine host, and restoring my data.
When oVirt team releases new releases, I'm just wondering if you test
going from the last previous release (4.3.10 in this case) to each
latest release?
Migration flows are tested for RHV, so it should work for oVirt if you wait
until the RHV version was released, and you have same RHEL-like version
as was tested with RHV.
I know that the documentation says we always need to
make sure we update to each individaul major release, but I'm just
wondering if this is something that oVirt team tests with each release?
I'm very concerned for potential of failed upgrade, and the potential
headaches that it could cause.
I see the 4.4.6 was released in time with RHEL 8.3. I'd like to use
Rocky Linux 8.4 because I believe RHEL has re-enabled mptsas (though I
know still unsupported) from 8.4+ which will make things easier.
RHV 4.4.6 was released with RHEL 8.4, and is oVit 4.4.6 compatible with
RHEL 8.4, so it should work with any REHEL 8.4-like distro.
But note that oVirt uses the advanced virtualization stream, providing
libvirt 7.0.0 and qemu-kvm 5.2.0:
http://mirror.centos.org/centos/8/virt/x86_64/advanced-virtualization/Pac...
Looking in Rocky packages, this is not available yet:
https://download.rockylinux.org/pub/rocky/8/AppStream/x86_64/os/Packages/
To replace Centos as the production OS for oVirt, the community must also
rebuild advanced virtualization.
You can try to use Rocky and pull in the advanced-virtualization repo from
Centos as a temporary solution.
