B<Quirk>: Device unplug is asynchronous in most cases and requires guest
cooperation. This means that it's up to the discretion of the guest to disallow
or delay the unplug arbitrarily. As the libvirt API used in this command was
designed as synchronous it returns success after some timeout even if the device
was not unplugged yet to allow further interactions with the domain e.g. if the
guest is unresponsive. Callers which need to make sure that the
device was unplugged can use libvirt events (see virsh event) to be notified
when the device is removed. Note that the event may arrive before the command
returns.
