Today I tried to downgrade systemd to 239-18 and then upgrade again to
see what will happen.
Please do not upgrade again, systemd 239-18 is the version used in CentOS 8.1, and oVirt-4.4 is targeting CentOS 8.1 currently.
That openvswitch-2.11.1-5.el8.x86_64 does not work flawless on CentOS Stream is documented on
If you like to test on CentOS Stream, there is an experimental repo in
which might change, disappear, or break your installation.
And yes, it is definitely caused by change in
systemd. Likely this change (BZ 1778384):
https://github.com/systemd-rhel/rhel-8/pull/44
But I don't know where to report the problem for CentOS Stream. The
'openvswitch' component in Bugzilla is not active anymore. Does anyone
know what's the proper component?
