When Panel is installed to PVC, administrators refer to Panel when performing web hosting operations and to Parallels Power Panel (PPP) when managing their container. The PPP becomes available when the administrators turn on offline-management mode. When this mode is on and Panel is installed, some controls and menus of PPP become available on top and left navigation panes of Panel. In other words, PPP partially builds into Panel in offline-management mode.
Since Panel 10, the integration between panels leads to unexpected results. For example, some icons in Panel might not be displayed or layout might be broken when the offline management is on. To resolve these problems, we recommend that you do not use the integration and access the panels on different ports (4643 and 8443).
To make PPP and Panel operate on different ports, do the following:
vzctl set CT_ID --offline_management yes --offline_service vzpp --save
vzctl set CT_ID --offline_management yes --save
vzcfgt set CT_ID offlineservices vzpp
