14.7.9. Detaching a Node Device

download PDF
The virsh nodedev-detach detaches the nodedev from the host so it can be safely used by guests via <hostdev> passthrough. This action can be reversed with the nodedev-reattach command but it is done automatically for managed services. This command also accepts nodedev-dettach.
Note that different drivers expect the device to be bound to different dummy devices. Using the --driver option allows you to specify the desired back-end driver.
