Symptoms

When I open Parallels Virtual Automation, Power Panel or Parallels Management Console current usage of performance counters are shown as n/a (not available).

In PVA agent logs you can explore the following errors:

Cause

The reason of the problem is broken Virtuozzo counters.

Resolution

To repair counters, please follow these instructions:

  1. Rename the following registry branch to old:

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VzPerf\Performance]

    • VzPerf.Ini
    • VzPerf.Reg

  5. Run vzperfsetup.exe /l VzPerf.Ini 1

  6. Restart VZAgent service:
