Public bug reported:

After I do volume operations as the following order:
1) start an instance
2) attach a volume to the instance
3) pause the instance
4) detach volume
5) unpause the instance, the volume is not detached correctly with libvirt.

When instance in paused state, it's actually active, so in libvirt
driver the VIR_DOMAIN_AFFECT_LIVE flag should be added  as the device
detach flag.
