Resolution

To simplify the usage of Parallels Power Panel (PPP) by a container owner, PPP web interface can be accessible on IP address of the container. By default, port 4643 is used. If the container has IP address 192.168.0.1 the PPP management interface is accessible by https://192.168.0.1:4643 even if the container is stopped. PPP accessibility on IP address of the container is controlled by per-container configuration parameter OFFLINE_MANAGEMENT. By default, it is set to "yes". To enable/disable it for the container #101 use the following commands:

# vzctl set 101 --offline_management=yes --save
# vzctl set 101 --offline_management=no --save

 

Virtuozzo Power Panel has the following login mechanisms:

  • If OFFLINE_MANAGEMENT parameter is set to "yes", PPP accepts the container "root" login with the corresponding password when connecting to IP address of the container.
  • If OFFLINE_MANAGEMENT is enabled and Plesk Control Panel is installed in the VE - logging in the container using Plesk credentials (user 'admin' with the corresponding password) is supported on IP address of the container. In this case, however, the management capabilities available via web interface are limited.
  • The Service Container administrative credentials (user 'vzagent0' with the corresponding password) are supported as well. Upon administrative login all containers on the Node are manageable.
When offline management is on for the container and it has Plesk installed, Plesk panel interface works via Service container (in other words, port 8443 is forwarded to Service container). In this case some additional Virtuozzo-related functionality is added to Plesk interface.
