| Thread-topic: | Driver domain questions |
What is a driver domain? Is it an unprivileged DomU that has access to a PCI device as described in user doc section 5.3? In that case can the device it is using be virtualized for other DomUs? (I guess not but I just want to be sure there is no magic that can make this happen. ☺) I understand that HVM Domains cannot have direct access to a PCI device. What needs to be done to make this happen? From a prior discussion with Mats, I guess there needs to be a way to inform the HVM domain of the existence of that PCI device. Does a PCI frontend need to be written for the HVM domain and OS drivers need to be made "virtualization aware"? Or is it enough to just have a PCI frontend and off the shelf drivers can be used?
