Description

A customer requested support for this feature(s).
Currently we emulate a Qemu virtual cpu, which allows us to migrate even between different CPUs on the hosts

Research, which CPU flags we can easily pass through or enable, by keeping the possibility to migrate between different hosts.

Alternatively:

Make a list of hosts that have compatible CPU features and cluster them (3+ per cluster)

Also keep in mind that native CPU support might benefit customers in terms of performance in general.
