Hi! Epyc is not available in oVirt-4.2. If you can recover the system and can upgrade to oVirt-4.3 it then you can switch to Epyc (I have system with Epyc's running in 4.3). For recovery I would try to roll back changes you did to database. -Juhani -Juhani On Mon, Jun 10, 2019 at 11:46 AM <sandeepkumar86k(a)gmail.com&gt; wrote: > > Hi, > > I am having trouble in fixing the CPU type of my oVirt cluster. > > I have AMD EPYC 7551P 32-Core Processor hosts(x3) in a gluster cluster.
