You said UUID is a general way to represent an object. VM is an object.
There is UUID associated with a VM. But UUID is not recorded in the
kernel KVM. It's a good reference to our design on vgpu object. If
one thing can be done in user space, then better not involve kernel side.

Even Qemu doesn't make UUID as mandatory. It's just an optional parameter.
I'm not sure why you insist UUID mandatory for vGPU here.

Paul/Malcolm are experts in Citrix XenServer. So I think they may give some
suggestions from their angle. :-)
