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

<div dir="ltr">Hi guys,
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Can I mix CPU types (Haswell and Sandy Bridge) in my
cluster and will I be able to migrate between my hosts?</div>
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>Apologies if this is a dumb question or if it's been
answered before.</div>

<div>Thank you.</div>
