Re: [ovirt-users] Mixing CPU types

Sure would be a nice feature, though! It would simplify things for those of us who build out of re-purposed Windows servers (still a lot of life left in them for Linux applications!) and end up with a mix of CPUs. For most of my VMs I don't need the latest and greatest CPU features, but being able to consolidate my hosts into fewer clusters would be really useful. Like you said, oVirt already allows mixing CPU generations by selecting the lowest common denominator CPU type -- as long as you stick to Intel or AMD. It's a similar scenario, and the KVM stuff seems well established. Just expose some additional "generic" CPU types, per the KVM docs, and allow mixed clusters... -- Matthew Trent Network Engineer Lewis County IT Services 360.740.1247 - Helpdesk 360.740.3343 - Direct line ________________________________________ From: Martin Polednik <mpolednik(a)redhat.com&gt; Sent: Wednesday, February 3, 2016 11:43 PM To: Matthew Trent Cc: Yaniv Kaul; users(a)ovirt.org Subject: Re: [ovirt-users] Mixing CPU types ----- Original Message ----- That is pretty much what libvirt does. The sandy-bridge, haswell and other cpu's that we expose are not really a CPUs, but sets of flags (called baseline CPUs in libvirt's terminology). Afaik there should be no issue running cluster with both CPU vendors, the problem is lack of testing on devel side as we mostly run single vendor clusters everywhere.
