Hi,

oVirt 4.2 works only on CentOS 7.6. If you want to upgrade your CentOS to 7.7, you need to upgrade also oVirt to 4.3, which I highly recommend as oVirt 4.3 provides huge number of bug fixes and improvements over 4.2.

Hello all, good afternoon.

I'm new here, my name is Wagner and I live in The Netherlands.

I inherited an old 4.2 oVirt cluster and I'm in process of adding new CentOS hypervisors to it. Sadly this isn't working well due to a conflict in vdsm and sos.

I did some research, and found this[1] on RedHat and also this thread[2] and this gerrit review[3]. Looks like the sos package now contains vdsm sos module and this needs to be removed on 4.2 version. Current sos package conflicts[4] with vdsm <= 4.30.17.

The way forward (if this is accepted by you and CentOS) would be to release a new 4.2 version, and change the conflict on sos package to accept this new 4.2 vdsm version. I can help with pull requests, building packages (.src.rpm) or whatever. What you guys think about it?
