libvirt dislikes detach ordering #1

Open chrisharper opened 4 years ago

chrisharper commented 4 years ago

The command detaches the device AFTER udev has begun unbinding. It seems virsh tries to cleanup some state and cant because by that time the device is gone from the host .

Doesn't seem to be any consequences of this so far other that errors.

The device is still removed from the guest usb port just seems the remapping of the device itself back to normal cannot happen as its now gone from the host.
