The ovirt log shows the update disk failed: ACTION_TYPE_FAILED_VM_IS_LOCKED. Expected results: Allocation policy changed as drop down indicates, or warning that the disk update command failed. Additional info: Attempted with VMs that were on, or off. Found in 3.6.2, also reproduced in separate enviroment of 3.6.3
The bug is not the fact that the allocation policy cannot be changed since we never supported a change in the allocation policy, the actual bug resides in the fact that fields that cannot be updated appear as changeable (Allocation Policy, Size and more). Investigating now, but this is the actual regression here.
