Description of problem:

I failed live migration disk because of a libvirt bug: 
https://bugzilla.redhat.com/show_bug.cgi?id=888426

After I shut down the vm and tried to delete it and we are still failing the delete in vdsm. 

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

libvirt-0.10.2-13.el6.x86_64
vdsm-4.10.2-3.0.el6ev.x86_64

How reproducible:

100%

Steps to Reproduce:
1. run a vm 
2. move the disk
3. shut down the vm and try to remove it 
  
Actual results:

we cannot remove the vm

Expected results:

we should be able to remove the vm regardless of any failure. 

Additional info: logs
