Symptoms

The Parallels Virtuozzo Power Panel (VZPP) is not working correctly for containers.

Resolution

There are several posible solutions:

  1. Restart the Parallels Virtual Automation Power Panel Director service :

    net stop pvapp && net start pvapp

  2. Makes sure that offline management is enabled globally on the node and the enabled offline services include 'vzpp' :

    C:\vzcfgt get 0 offlinemgmt
1

    If necessary, enable it (if the output of the previous command is "0") :

    vzcfgt set 0 offlinemgmt 1

  3. Reconfigure the Power Panel website :

    "C:\Program Files (x86)\Parallels\Parallels Virtual Automation\Power Panel\bin\pp-config.exe" postinstall

  4. Make sure there are proper registry entries for port redirections:

    C:\>reg query HKEY_LOCAL_MACHINE\SOFTWARE\SWsoft\Virtuozzo\Redirect

HKEY_LOCAL_MACHINE\SOFTWARE\SWsoft\Virtuozzo\Redirect
    vzpp    REG_SZ    0:4643
    vzpp-plesk    REG_SZ    0:8443
    vzpp-sb    REG_SZ    0:2006

    If not, add them :

    reg add HKEY_LOCAL_MACHINE\SOFTWARE\SWsoft\Virtuozzo\Redirect /v vzpp /t REG_SZ /d 0:4643
reg add HKEY_LOCAL_MACHINE\SOFTWARE\SWsoft\Virtuozzo\Redirect /v vzpp-plesk /t REG_SZ /d 0:8443
reg add HKEY_LOCAL_MACHINE\SOFTWARE\SWsoft\Virtuozzo\Redirect /v vzpp-sb /t REG_SZ /d 0:2006

  5. Reset the offline management settings for the containers which are not working :

    vzctl set CTID --offline_management no --save
vzctl set CTID --offline_management yes --save

    To do this for all containers on the Hardware Node at once :

    for /f %i in ('vzlist -Hao veid') do vzctl set %i --offline_management no --save && vzctl set %i --offline_management yes --save

  6. Check the problem at a network level.

    Make sure that the connection to the Hardware Node on port 4643 can be established from outside the node.

    telnet <node_ip_address> 4643

    Try to open the Power Panel from the Virtualization node where container is running.

  7. If a Service Unavailable error message is displayed when you open Power Panel, open Internet Information Services (IIS) Manager and make sure the ASP.NET 1.1 Application pool is running.

  8. Check that a valid certificate is selected for bindings in IIS manager on the node for PVA Power Panel Web Site.
