Description Arik 2016-08-07 11:28:55 UTC

Description of problem:
I'm not sure why, but when trying to update a VM that was set to preview a snapshot the engine tries to edit its disk and therefore we get in the webadmin the following error although the update (in this case of memory) succeed:
Cannot edit Virtual Disk. VM is previewing a Snapshot.

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


How reproducible:
100%

Steps to Reproduce:
1. Preview a snapshot
2. Update the memory of the VM
3.

Actual results:
The update succeed but we get in the webadmin the error mentioned above.

Expected results:
The update should succeed with no error.
