The vgpu code doesn't need to associate the vgpu device with a vm in the
first place. You get all guest address space information from qemu, via
vfio iommu interface.
When qemu does't use kvm (tcg mode), things should still work fine.
Using vfio-based vgpu devices with non-qemu apps (some kind of test
suite for example) should work fine too.
cheers,
Gerd
