Thanks for posting this report.

The log is from the source of migration, right?
Could you trace the history of the hosts of this VM? Could it be that it
was started on an older version of vdsm (say ovirt-3.3.0) and then (due
to migration or vdsm upgrade) got into a host with a much newer vdsm?

Would you share the vmCreate (or vmMigrationCreate) line for this Vm in
your log? I smells like an unintended regression of
    http://gerrit.ovirt.org/17714
    vm: extend shared property to support locking

solving it may not be trivial, as we should not call
_normalizeDriveSharedAttribute() automatically on migration destination,
as it may well still be apart of a 3.3 clusterLevel.

Also, migration from vdsm with extended shared property, to an ovirt 3.3
vdsm is going to explode (in a different way), since the destination
does not expect the extended values.

Federico, do we have a choice but to revert that patch, and use
something like "shared3" property instead?
