Interesting idea. Don't think that would work for multi-socket boards though, which I think are most servers.

Ah, didn't see the restriction to single socket boards but that makes sense. Probably not going to work for any of the major cloud providers then.

It could work intermittently depending on which vCPUs your VM or covert channel apps get assigned (intermittently as that could change unless your hypervisor uses CPU pinning...)
