[ovirt-users] Re: Ignore CPU_TYPE_UNSUPPORTED_IN_THIS_CLUSTER_VERSION ?

Actually the inability to mix CPU vendors is increasingly becoming an issue, and probably not just for me. Of course this isn't an oVirt topic, not even a KVM-only topic, but reaches deep into the OS and even applications. I guess Intel rather likes adding extensions and proprietary registers/flags as long as it plays in their favor, but with enough clouds and DCs going to EPYC that might flip on them one day. And in terms of actual instruction support, there should be a rather larger intersection of true shared ISA between the two than the last true common ancestor (80486?) implies, which could be defined as abstract machine types by hypervisor vendors. The other day I managed to trick a Ryzen 9 via a VMware configuration into appearing an Intel CPU well enough to run a Hackintosh that doesn't like AMD (CPUs), so it's a definite possibility.
