I have a few options in mind: - failing registration of a device and loading of guest if an already-loaded driver is found - Not worry about this case and leave it to the administrator The first option can be enforced by calls to pci_enable_device() and pci_request_regions(). This can solve the problem of assigning multiple devices of the same guest as well. Dynamically unbinding devices is prone to a lot of errors and assumptions and such policy shouldn't be enforced. We should either fail the assignment and let the administrator take care of doing the right thing and start the guest or just not launch the guest at all.
