Think about what you are asking first. A VM is a virtual machine that theoretically is separated from the base hardware. I don't think a VM is the solution for Bios Updates or changing bits on the physical hardware itself. Of course, you can monkeypatch the VM's bios all you want! But that would be erased the next time you start a new vm. The only other way is to find a security hole in KVM, qEMU, or XEN, and then exploit it to break out of the VM[1] and get access to base hardware. Hard to do, but it does happen.
