Hi,

I am currently building a new virtualization cluster with oVirt, using AMD EPYC processors (AMD EPYC 7351P). At the moment I'm running oVirt Node Version 4.2.3 @ CentOS 7.4.1708.

We have the situation that the processor type is recognized as "AMD Opteron G3". With this type of instruction set the VMs are not able to do AES in hardware, this results in poor performance in our case.

I found some information that tells me that this problem should be solved with CentOS 7.5

--> <https://access.redhat.com/errata/RHEA-2018:1488>

My actual questions:

- Are there any further information about the AMD EPYC support?
- Any information about an update of the oVirt node to CentOS 7.5?

Greeting Tobias
