Didn't hear about multiple vGPUs for a single VM before. Yes If we
expect same vGPU interfaces for different vendors, abstraction and
vendor specific stuff should be implemented.

For the last assumption, yes, a VM id is not necessary for gvt-g, it's
only a temporary implementation.
As long as libvirt is used, UUID should be enough for gvt-g. However,
UUID is not mandatory? What should we do if user don't specify an UUID
in QEMU cmdline?
