Hi,
I am researching hardware for our virtualization platform (Proxmox) and i would like to see a list of Epyc CPU features (the ones listed in /proc/cpuinfo) to see if we can use it for live migration/HA with our mixed CPUs (I7-3770s, E3-1240 V2, E5-2620 v2) using the IvyBridge KVM CPU type.

Can somebody help me out with this?

Thanks

PS I suppose all Epyc CPUs have the same feture sets?
