Hi guys,
I currently have an oVirt 3.5 cluster with Sandy Bridge Xeon CPU's, and I
need to add a new host for more RAM and vCPU's, however the new Xeon e5
cpu's are Haswell based.
Can I mix CPU types (Haswell and Sandy Bridge) in my cluster and will I be
able to migrate between my hosts?
I'm guessing that for this to work I'll need to leave my "CPU type" set
to
Sandy Bridge, will the Haswell based CPU be compatible with my cluster, but
just run without any Haswell type features?
Apologies if this is a dumb question or if it's been answered before.
Thank you.
Regards.
Neil Wilson

Hi Neil,
You can mix cpu types (but not AMD and Intel) if you leave the cluster=20
level at the lowest cpu level.
I personally don't mix cpu levels if possible, but instead create own=20
clusters for each cpu type in order to be able to use the newest cpu=20
features...

Can I mix CPU types (Haswell and Sandy Bridge) in my cluster and will=20
I be able to migrate between my hosts?
