on stackoverflow i read that vmware and RHEV / oVirt already do this in
clusters.
"For mixed clusters, use the lowest available CPU version, so if one
host is Penryn and the other Nehalem, use Penryn on both. If you are
using RHEV or oVirt, this is already built in. VMWare have this called
"EVC" and position it as a huge feature."
I think somethink like this for proxmox instead of using kvm64 as a
default would be great!

Hi,
is there any way or has anybody thought about optimizing the cpu flags
in pve automatically?
Currently the default is kvm64 which is more like a very limited set of
cpu flags/features which qemu can software emulate.
For example on a modern intel CPU there is a really big bunch of
features missing for guests:
avx, sse3, sse4.1, sse4.2, aes, many more
Has anybody ever thought about optimizing this?
Stefan
