It looks like no-strict-reset=True has to be passed *every time* you attach a PCI device to a VM... that it was passed before when attaching to a different VM is not enough! Detaching all USB controllers from sys-usb and then manually reattaching with $ qvm-pci attach --option no-strict-reset=True --persistent sys-usb dom0:00_14.0 resulted in a slightly different error when trying to start sys-usb: $ qvm-start sys-usb Start failed: internal error: Unable to reset PCI device 0000:00:14.0: internal error: libxenlight failed to create new domain 'sys-usb', see /var/log/libvirt/libxl/libxl-driver.log for details $ sudo tail /var/log/libvirt/libxl/libxl-driver.log libxl: libxl_pci.c:1199:libxl__device_pci_reset: The kernel doesn't support reset from sysfs for PCI device 0000:00:14.0 However attaching all controllers to disp-sys-usb (using the above command) worked, and my USB devices are recognized by disp-sys-usb. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
