[pve-devel] Optimizing CPU flags

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
