After installing PVC updates and rebooting the node, Parallels Virtuozzo Containers Management Service cannot start.

In the Event Viewer the following message is observed:

Log Name: System
Source: vzcore
EventID: 1
Level: Error
Logged: 01/04/2014 22:05:32
The description for Event ID "1" from the source "vzcore" was not found. Either the component that raises this event is not installed on the local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

C0000058 = ZwOpenDirectoryObject (\ VPS) failed

Similar error message could be found in C:\vzlog\YYYY.MM.DD-vzlog.log:

T=2015.05.05 23:33:31.491; A=vzksal; P=700.720; S=VzKSAL; F=rtserver.cpp,KsalHandler<class KsalMsgSymAddress>::Process,902; L=ERROR; R=7(7); C=0(0); M=7 [] Failed resolve module name for symbolId:(115307)


Parallels Virtuozzo KSAL database does not match the installed update.


  1. Locate C:\Program Files\Parallels\Containers\Extras\ksaldb.dat file and check its modification timestamp.

  2. Find all ksaldb.dat files that belong to the most recent updates. Run the following command in command prompt:

    C:\>where /r "C:\Program Files (x86)\Parallels\PVC updates" ksaldb.dat

    Check 2-3 locations from the last lines in the output and compare the timestamp with the active one (found in step 1).

  3. If there's a newer version of KSAL, it is necessary to reinstall the recent updates in correct order: uninstall the updates, reboot the node, install the update in correct order, reboot the node again.
