Description of problem:
During a successful Live migration a failed teardown error is reported


Version-Release number of selected component (if applicable):


How reproducible:

System description:
Environment Structure:

1 DC, 2 Clusters attached to it
3 virtual hosts attached to the first cluster
3 NFS SDs
1 export domain
1 detached shared ISO
1 Glance external provider attached
1 template is imported from Glance
6 vms down (golden_env_mixed_virtio_*)
10 vms w/rhel6 running (STAYING_ALIVE_*)

We started with this environment structure on a 3.5 engine and the upgrade flow was done as:
engine: 3.5 -> 3.6 -> 4.0 -> 4.1
All this upgrade flow was done with the 10 running VMs kept alive and all hosts being upgraded to the relevant engine versions.


Steps to Reproduce:

1. Hot Plug 2 iscsi block disks (1 thin, 1 preallocated) to VM from template
2. Move both disks to another iscsi domain
3. Teardown error is reported during move which succeeds

Actual results:
Teardown error is reported during move which succeeds

Expected results:
Teardown should not fail
