Description of problem:
Any attempt to change any property of a running Linux VM which has been imported from RHEV 2.2 fails with "Failed updating the properties of the VM.".

/var/log/ovirt-engine/engine.log shows the following:
ERROR [org.ovirt.engine.core.utils.ObjectIdentityChecker] (ajp-/127.0.0.1:8702-15) [de80ed8] Field timeZone can not be updated when status is Up
WARN  [org.ovirt.engine.core.utils.ObjectIdentityChecker] (ajp-/127.0.0.1:8702-15) [de80ed8] ObjectIdentityChecker.IsUpdateValid:: Not updatable field 'timeZone' was updated
WARN  [org.ovirt.engine.core.bll.UpdateVmCommand] (ajp-/127.0.0.1:8702-15) [de80ed8] CanDoAction of action UpdateVm failed. Reasons:VAR__ACTION__UPDATE,VAR__TYPE__VM,VM_CANNOT_UPDATE_ILLEGAL_FIELD

Version-Release number of selected component (if applicable):
rhevm-backend-3.2.1-0.39.el6ev

How reproducible:
Always

Steps to Reproduce:
1. Export a Linux VM from RHEV 2.2.
2. Import that Linux VM in RHEV 3.2.
3. In webadmin portal go to "Virtual Machines", select the VM and click "Edit".
4. Try to change any property and click OK.

Actual results:
<vm_name>:

    Failed updating the properties of the VM. This may be caused either by:
    1. The values selected are not appropriate for the VM; or
    2. Its values cannot be updated while the VM is in UP state (Please shut down the VM in order to modify properties such as CPU or cluster).

Also /var/log/ovirt-engine/engine.log shows the following:
ERROR [org.ovirt.engine.core.utils.ObjectIdentityChecker] (ajp-/127.0.0.1:8702-15) [de80ed8] Field timeZone can not be updated when status is Up
WARN  [org.ovirt.engine.core.utils.ObjectIdentityChecker] (ajp-/127.0.0.1:8702-15) [de80ed8] ObjectIdentityChecker.IsUpdateValid:: Not updatable field 'timeZone' was updated
WARN  [org.ovirt.engine.core.bll.UpdateVmCommand] (ajp-/127.0.0.1:8702-15) [de80ed8] CanDoAction of action UpdateVm failed. Reasons:VAR__ACTION__UPDATE,VAR__TYPE__VM,VM_CANNOT_UPDATE_ILLEGAL_FIELD

Expected results:
Properties are updated successfully.

Additional info:
.OVF files created by RHEV 2.2 in export domain during export contain a value for the Windows domain field:

$ xmllint --format 0a559483-5c1f-42b3-a895-ee8250a7f6e4.ovf | egrep -i "domain|timezone"
    <Domain>MYDOMAIN</Domain>
    <TimeZone/>

RHEV 3.2 should disregard Windows domain for Linux VMs.

Workaround is to stop engine service, update the database by ensuring that Windows domain and timezone properties are set to NULL and start engine service back:

engine=# update vm_static set domain=NULL, time_zone=NULL where vm_name='<vm_name>';
