  • Applies to:
  • Odin Business Automation Standard 4.5
  • Plesk Automation 11.5
  • Plesk 12.5 for Linux
  • Plesk 12.0 for Linux
  • Plesk for Windows
  • Virtuozzo containers for Windows 6.0
  • Virtuozzo containers for Windows 4.6


When Parallels Virtuozzo Containers are installed on the node, and Plesk is running in one of the containers, the port 8443 (used by Plesk) is redirected to Parallels Virtual Automation installed on the PVC node. As a result, applications listening on this port inside the container are not accessible.

Another case when it could be necessary to disable redirection is when an old Plesk version (below 7.6.1) or recent Plesk version (10.0 or later) is used, which does not support this type of redirection.


There are several ways to disable PVA-Plesk redirection. Please use the most suitable for the running configuration:

  1. Disable redirection of 8443 port for the specific container, but leave redirection of Power Panel (port 4643) (requires container restart):

    > vzctl stop CTID
    > vzctl set CTID --offline_management no
    > vzctl set CTID --offlineservices vzpp
    > vzctl set CTID --offline_management yes
    > vzctl start CTID 
  2. Disable all redirection for the specific container, for both Power Panel (port 4643) and VZPP-PLESK (port 8443) (does not require container restart):

    > vzctl set CTID --offline_management no    
  3. Disable all redirection for ALL containers (does not require container restart):

    > vzctl set 0 --offline_management no   
  4. Disable redirection of 8443 port for ALL containers, but leave redirection of Power Panel (port 4643) (requires restart of all containers (or restart of the node)):

    • Stop all VEs
    • Stop Virtuozzo Management service:

      > net stop vzsrv
    • Disable redirection in global configuration:

      > vzcfgt set 0 offlineservices vzpp
    • Restart the Hardware Node
