Hi,

As mentioned to run oVirt Engine 4.5 you need at least on EL8.6 or CS8 
machine. Then you can create DataCenter with compatibility level 4.2, 
where you can create 4.2 cluster.

Hi Andrei,

ovirt 4.4+ has to run with centos/ rhel 8, I would not

And yes cluster compatibility version number doesn't match

I would recommend to try to remove the oldest node from the
cluster (if

standalone engine for test if it works or not.

 yes, you generally need the latest version

Hi Martin,

then I'm a bit confused :D in ovirt doc is  written.

see

and when I have a fresh oVirt4.5 installation there is cluster 
compatibility version 4.2 not available.

Hi,

Martin, thanks a lot, now I successfully upgraded Engine to latest 4.5, yet old 
nodes 4.2 / CentOS 7.6 still working fine.
Now I can move VMs and upgrade old nodes.

Hi,

1. Supported cluster levels
- oVirt Engine 4.5 supports cluster level 4.2 - 4.7

https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/compat/src/main/java/org/ovirt/engine/core/compat/Version.java#L22
- This means that both EL7 based (4.2 and 4.3) and EL8 based (4.4-4.7)
hosts can be successfully managed by oVirtEngine 4.5

2. OS requirements of oVirt Engine 4.5
- oVirt Engine 4.5 is supported only on EL 8.6+ and CS8 stream
- This means that:
- for standalone engine you need to have a machine with EL8.6 or CS8
- for hosted engine you need to have a cluster with EL8.6 or CS8
hosts, where hosted engine VM based on E8.6 or CS8 can run

So specifically for your use case you need:

2. Hosted engine 4.5 running on cluster of EL8.6 or CS8 hosts with

[ovirt-users] Re: Q: Engione 4.4.10 and New Host on CentOS Stream 9

2022-08-29 Thread Jirka Simon 

Hi Andrei,

ovirt 4.4+ has to run with centos/ rhel 8, I would not recommend mix 
versions of ovirt node version within one cluster. (there couldbe / will 
be a problem with vdsm version on each node)


And yes cluster compatibility version number doesn't match  ovirt version.

I would recommend to try to remove the oldest node from the cluster (if 
upu have some spare nodes) and try to reinstall it to centos 8 or 9 with 
standalone engine for test if it works or not.

Looks like oVirt Engine version and cluster compatibility level do not match 
number to number, e.g. my oVirt engine 4.4.10 seems can set cluster 
compatibility level up to 4.6.

Someone from Red Hat, please clarify.
Thanks in advance.

it means i created new cluster with fresh configuration with ovirt 4.5  and 
cluster compatibility version 4.7 next to old one with 4.4.   Iit is a good 
opportunity to prepare whole cluster configuration in ansible for me :D

Then I migrate VMs one by one from old cluster to the new one. When is one node 
free on old cluster I reinstall it and add to new cluster.

Maybe it is not the fastest solution, but i can arrange maintenance for each VM.

yes, you generally need the latest version
You can keep your old nodes old, 4.2 based nodes are still working with 4.5
