I've got my external USB hub on the controller at 43:00.0, the bus is 07 and the port is 0. My XML looks like this: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x07' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x10' function='0x0'/> </hostdev> When starting the VM, I get this error: Device 0000:07:00.0 not found: could not access /sys/bus/pci/devices/0000:07:00.0/config: No such file or directory Also noted is the fact that it doesn't show up in /sys/bus/pci/devices in an ls (see attached) I've also attached proof of the bus (the second screenshot). Update: that device is a dummy: ot: 00:07.0 Class: Host bridge Vendor: Advanced Micro Devices, Inc. [AMD] Device: Family 17h (Models 00h-0fh) PCIe Dummy Host Bridge NUMANode: 0 And the real device is 43:00.3, but unRAID doesn't let me type over 1F (43=2B) <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x07' slot='0x2B' function='0x3'/> </source> </hostdev> Note: upon changing the second slot (the automatically generated one after </source> to 0x00 errors out with an XML error saying it needs to be >=1.
