Description of problem:

The Administration Portal allows a user to try to migrate the HE VM Disk. It fails on Validation, as expected, but the Disk remains in Locked State and now the VM cannot be Migrated anymore.

Version-Release number of selected component (if applicable):
ovirt-engine-4.0.4

How reproducible:
100%

Steps to Reproduce:
1. Click on Hosted-Engine VM
2. Click on Disks Tab
3. Select Disk
4. Click Move
5. Select Destination, Click OK
6. Fails (Expected and Correct)
7. Disk Remains in Locked State
8. Click Migrate -> Fails
8. VM cannot migrate, it's stuck:
Cannot migrate VM: The following disks are locked: virtio-disk0. Please try again in a few minutes.

Actual results:
It fails when Validating (as expected), but should not leave the Disk in Locked State

Expected results:
Fails or Blocked. Disk in OK state.

Please attach Engine logs.
Also, which validation is failing that is expected to fail?

Hi Tal,

The image is left locked at the end of the process.

engine=# select imagestatus from images where image_group_id = '55e10183-51d7-4f74-8cef-8fe21cd4f5ed';

* Validation: the validation step for executing the disk move (snapshot for live migration), in the engine.
