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
