Hi Gianluca,
As mentioned in below RFE, EL 8.4 is not enough, you also need Advanced
Virtualization 8.4 (libvirt >= 7.0.0) and AFAIK this has not been released
upstream:
https://bugzilla.redhat.com/show_bug.cgi?id=1933974
So right now you can use 4.6 cluster level only on hosts running on CentOS
Stream.
Also the error message tells you that all your Up hosts need to provide EL
+ AV 8.4 features before you upgrade cluster level. But of course you can
upgrade them one by one, it's not required to put all hosts into
Maintenance before upgrade.
Regards,
Martin

Hello,
I updated all my 3 CentOS 4.4.5 hosts to 4.4.6.
Or at least upgrading them from the GUI I see now they are on CentOS 8.4
and:
[root@ov200 ~]# rpm -qa| grep 4.4.6
ovirt-release44-4.4.6.3-1.el8.noarch
ovirt-host-4.4.6-1.el8.x86_64
ovirt-host-dependencies-4.4.6-1.el8.x86_64
[root@ov200 ~]#
How to see from the webadmin GUI or from the Host Console that they are
indeed 4.4.6?
If I try to set cluster compatibility version to 4.6 I get:
Error while executing action: Cannot change Cluster Compatibility Version
to higher version when there are active Hosts with lower version.
-Please move Host ov300, ov301, ov200 with lower version to maintenance
first.
I don't remember the need of giving downtime to get new cluster version...
Or what are further requirements (and benefits....) to upgrade to 4.6?
Thanks,
Gianluca
