Could be a v1, but figured I'd get feedback first - I have a "working
example" for QEMU (supported since 2.9.0), but it's not quite ready
to be fully posted. Currently only needed for windows guests, but
there is some work upstream (somewhere) to make a Linux implementation.

Still have to work out all the various "combinations" of when to
add the vmgenid device and I think there's one combination that's
not quite possible and may require some sort of set vmgenid guid
value qmp command (that's being debated on qemu upstream now).

To read up on the QEMU implementation, see from the top of a 
QEMU source tree:

    docs/specs/vmgenid.txt

The (ahem) Microsoft details on the device is found at:
