How reproducible:
100%

Steps to Reproduce:
1. Prepare a guest which has installed virt-v2v on OSP16.2 environment, we call the guest as 'v2v-appliance'
$ openstack server list

2.Convert a guest from VMware to OSP16.2 by virt-v2v

3.Try to launch the volume as instance on OSP16.2 dashboard after v2v conversion, but found the status of volume is in-use, the volume can't be detach from v2v appliance automatically, pls refer to screenshot"volume-cannot-detach-after-v2v-conversion"


Actual result:
As above description

Expected results:
The volume should be detached from v2v appliance automatically after v2v converting guest to OSP16.2

Additional info：
1.Can't reproduce the bug on OSP16.1
