Parallels Virtualization and Automation Software

SYMPTOMS

Some VEs stop extremely slow.

CAUSE

The possible reason is terminal server registry settings set for the current VE.

"HKLM\vz%VPSID%\MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services"

KeepAliveEnable

KeepAliveInterval

RESOLUTION

Remove the registry values above:

To remove such values automatically for all VEs C:\Program Files\SWSoft\Virtuozzo\bin\on_vps_startup.cmd  file should be edited. It’s necessary to add the following code almost to the very end of on_vps_startup.cmd  before goto quit_cmd string :

REM

REM    Deleting  "KeepAlive..." value  - causes a long delay on VPS stop

REM

reg delete "HKLM\vz%VPSID%\MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v KeepAliveEnable /f

reg delete "HKLM\vz%VPSID%\MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v KeepAliveInterval /f

Note: Please back up original on_vps_startup.cmd  file before doing any changes.
