Oh this is interesting, i will definitely try this. Even if it is not exposed to libvirt we can pass custom command line parameters via xml. Thanks a lot! Rokas Kupstys On 2016.08.24 03:31, Samuel Holland wrote: > Hello, > > On 08/23/2016 02:07 AM, Rokas Kupstys wrote: >> Is it possible to pass-t

Just to chime in, yes and no. You can't pass a port, you can pass a single device, but it's best to pass a whole USB controller. I also picked up a USB PCIe card for vfio use, it has two USB 3.0 ports on the PCI bracket and a header for two front mounted ports, and I have labels from my Brother lab

You can't pass the port itself. You can pass individual devices attached to a port, but the latency can get weird sometimes. I had pretty significant problems when I did it that way. I opted to use Francisco's solution above, with a slight adjustment. I have a dedicated card that gets allocated

Is it possible to pass-through USB port? I know we can pass-through specific usb devices or entire usb controllers however it is not ideal in all cases. For instance in my case single pci device drives all usb ports on the back panel. Naturally i cant pass-through that pci device because it would l
