Description of problem:
The engine refuses to change the disk editing the engine VM.
This is needed by the upgrade flow of hosted-engine from 3.6/el6 to 4.0/el7:
in the upgrade flow we are creating a new floating disk and we are deploying here the 4.0 appliance were we'll restore the engine backup.
Only at the end, if and only if everything id fine, we use engine 4.0 to edit the engine VM to permanently point to the new disk.

We saw it only since 4.0.0.4-0.1.el7ev, in previous releases it was working for spice and silently failing for vnc.
Marking it as regression.
Version-Release number of selected component (if applicable):
4.0.0.4-0.1.el7ev
How reproducible:
100%
Steps to Reproduce:
1. deploy hosted-engine 3.6
2. try upgrading to 4.0
3.
Actual results:
it fails with: Operation Failed: [There was an attempt to change Hosted Engine VM values that are locked.]
Expected results:
The engine correctly switch the engine VM disk.
Additional info:
This blocks the hosted-engine upgrade flow from 3.6/el6 to 4.0/el7

Bug tickets must have version flags set prior to targeting them to a release. Please ask maintainer to set the correct version flags and only then set the target milestone.
So far I added AddDisk and HotPlugDiskToVm to the list of actions HE VM is allowed to perform. It works but the OVF conversion in ovirt-ha-agent needs a fix to properly support > 1 disk.
The hosted engine disks upgrade will be performed differently, generally by swapping the disk content with the new one. The disk, with its ID remains the same.
So the functionality of adding/removing disks for the HE VM is off the table, we don't need that. If needed we should open a proper RFE for that.
