From my point of view it is better to have slower cpu performance and
possibility to use all of our servers in cluster. I would like to have
live migration available from intel to amd. The problem is only in cpu
instruction sets? If so, I can use only common sets.
the problem is afaik kvm doesn't really support it for live migration
(other than a prototype several years ago).
Another feature which I forgot is network between VMs and mirroring
traffic. Both configurable from WUI.
port mirroring is supported today?
