is that your kernel could be hypervisor aware?
Could you compile a kernel that flags itself as being in a critical region all the time? Would that give you a whole CPU indefinitely?

Dunno however how scheduling factors into it—I was under the impression that VMs are treated much like userland programs. I.e. would similarly be scheduled off sooner or later.
