The cause of the issue is incompatibility of Virtuozzo Agent 4.0 (provided by Parallels Infrastructure Manager, PIM 4.0) with Virtuozzo Agent 4.6 (provided by Parallels Virtual Automation, PVA 4.5/4.6). The problem occurs if Virtuozzo server with PIM 4.0 is trying to backup a container to the node with PVA.
