You can bind it to any PCI device, but have to write userspace driver for such device using vfio driver interfaces. Packaging Contents. It's reason for being is that there is no other centralized database of PCI device IDs. Furthermore, these devices are the first to support both hot-swapping and cold-sparing. If the network interface used by the primary domain is on a bus that you want to assign to another domain, reconfigure the primary domain to use a different network interface. The device must have an ID that will provide to the driver for identification, and the operating system must be able to identify these configuration changes as they appear. So, the other two buses, pci_2 ([email protected]) and pci_3 ([email protected]), can safely be assigned to other domains because they are not used by the primary domain. PCI function: one of a number of logically-independent parts of a PCI device. 2 specification and t he 5 V signaling still used by many systems. vfio support for guest page table binding request from VMs 3. – nowaqq Oct 29 '17 at 20:17.
