Expired OVS account

Recently an unmonitored OVMM machine (OVM 3.03 Manager machine - another VM in this case) ran out of disk on the root volume. Symptoms being exhibited were frozen VMs, and VMs not being able to start with the unhelpful message "Failed to begin a transaction". Otherwise monitored systems were behaving well. Once the source of the incidents was determined, and adequate free diskspace reclaimed, further resolution involved the following steps to unexpire the OVS account and resume the OVM manager to service.
