SymptomsRDP session is disconnected during Virtuozzo installation and never comes back to installation process after manual reconnection.
CauseMost likely the reason of the problem is custom Terminal Services Configuration which is configured to end terminal session when it is disconnected. The disconnect itself is caused by design of Virtuozzo and happens during vzbridge.sys driver installation.
Please go to Start, Administrative Tools, Terminal Services Configuration, Connections, right click on RDP-Tcp, go to Sessions tab and toggle off Override User Settings checkboxes, click OK.
Then it is necessary to log off from the session and log in again to apply new configuration settings.
After that please try to install Virtuozzo again.
