Comment 2 Avi Tal 2012-02-09 12:08:02 UTC 
The same NullPointerException appeared in rest_api test as well.
It appears in the following scenario:
1. NFS storage domain
2. add 8 different disks to the VM.
3. create snapshot1
4. create snapshot2
5. restore snapshot2 (through rest api we have only restore option)
6. remove snapshot1
7. remove 6 disks randomly
8. start VM

attached engine.log 


NOTE: it looks like the problem is with specific disk type after import or just some snapshot procedure.
