In order to troubleshoot issues with virtual machines and containers on a Virtuozzo server, it is useful to have verbose logging enabled.


  1. Check current log level:

    [root@vz ~]#  prlsrvctl info | grep log
    Verbose log: off
  2. Increase log level:

    [root@vz ~]# prlsrvctl set --verbose-log on
    The Server has been successfully configured.
  3. Reproduce the issue and decrease log level back:

    [root@vz ~]# prlsrvctl set --verbose-log off
    The Server has been successfully configured.
