Re: [ovirt-users] VM with attached host USB device failed to run

well, yes. But unless you share a bit about what your problem is I doubt it’s of any help… are you talking about passing through a host usb controller into a VM? Is your host capable of proper hardware device isolation? If not, it may need some workarounds. Going through [1] might help too, most of the constraints are applicable to USB passthrough as well Thanks, michal [1] https://mpolednik.github.io/2017/03/19/hostdev-passthrough-pci/
