Find suitable CPU / CPU family

Latest response

Hi all,

What is the easiest way to dertermine if a CPU is suitable in a RHEV-H host and what family it is?

Right now I try to figure out the family with values in /proc/cpuinfo and look them up in [1] / [2] (cpuid is not available on RHEV-H).

There must be an easier / better way to do this. Anyone?

 

Regards,

I'm not quite sure I follow. Are you looking for the CPU requirements as documented in the RHEV 3.1 Installation Guide? Are you looking for the command line check documented there to check whether virtualisation extensions are present and enabled?

# grep -E 'svm|vmx' /proc/cpuinfo | grep nx

Mapping model names to Intel product family names, well, I suspect that's a bit more complicated.

That is exactly where I am looking for ... but a common script to test a host for compatibilty (without installing RHEV-H) would also be fine. But my problem lies in getting the family name clear.

Just found an answer in the #oVirt IRC channel. Before you start your installation, you can boot the RHEV-H ISO and escape to a shell (F2). Then run:

# virsh -r capabilities

I tested this with the RHEV-H 3.1 ISO on supported HW and it worked. I didn't test this with unsupported HW yet. This command can be run on a running RHEV-H server aswell.

Great, Vincent! Thanks for following up with this answer.
