Public bug reported:

sorry post bug at wrong place.....

** Affects: neutron
     Importance: Undecided
         Status: Invalid

** Changed in: neutron
       Status: New => Invalid

** Description changed:

- we are using OpenStack Queens: 
- nova-common/xenial,now 2:17.0.9-6~u16.01+mcp189 all [installed]
- nova-compute/xenial,now 2:17.0.9-6~u16.01+mcp189 all [installed,automatic]
- nova-compute-kvm/xenial,now 2:17.0.9-6~u16.01+mcp189 all [installed]
- 
- guest vm uses windows 2012 datacenter edition
- 
- after successfully executing openstack server add volume ${instance_id}
- ${volume_id}, we observe volume status has changed to in-used and
- attachments info are correctly stored in both nova and neutron. But
- device does not show up in guest machine.
- 
- we execute `virsh dumpxml ${instance_id}` but device is not there. We
- then try to edit directly by executing `virsh edit ${instance_id}` and
- we see the device with proper attachments info...
- 
- At last we have to shutdown the vm and boot again to solve the problem.
- 
- 
- command line outputs are put below,
- 
- /var/lib/libvirt/qemu# virsh dumpxml 55 --inactive
- ....
-     <disk type='network' device='disk'>
-       <driver name='qemu' type='raw' cache='writeback' discard='unmap'/>
-       <target dev='vdc' bus='virtio'/>
-       <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
-     </disk>
- .....
- 
- # virsh domblklist 55
- Target     Source
- ------------------------------------------------
- vda        vms/xxx
- vdb        vms/xxxx
- 
- manually attach vdc reports `vdc` in-used
