             [--] <vserver> <command> <args>*
<vserver> is the name of a vserver.
Possible commands are:
    start [--rescue [--rescue-init] <rescue-cmd> <args>*]]
                ... starts the specified vserver
    stop [--rescue-init]
                ... stops the specified vserver
    restart     ... restarts the specified vserver; this is the subsequent
                    execution of a synchronized 'stop' and a 'start'
    condrestart ... restarts the vserver when it is running already
    suexec <user> <command> <args*>
                ... executes a command as the specified user in the vserver
    exec <command> <args*>
                ... executes a command as root in the vserver
    enter       ... executes the configured shell in the vserver
    chkconfig <chkconfig-options*>
                ... modifies the init-system; currently, only Red Hat's
		    chkconfig is supported
    running     ... succeeds iff the vserver is running
    status      ... gives out some human readable status information about
                    the vserver, and succeeds iff the vserver is running
    build <buildopts>*
                ... builds a new vserver from scratch, see
                    vserver ... build --help for details
    delete      ... remove a vserver
    unify [-R] <vunify-opts>*
		... (de)unify the vserver with its reference vserver(s).
    pkg install <pkg>
		... installs package(s) in the vserver
    apt-get,apt-config,apt-cache <apt-opts>*
		... execute the apt-* command for the given vserver
    rpm <rpm-opts>*
		... execute the rpm command for the given vserver
    pkgmgmt externalize|internalize [-y]
		... externalize or internalize the package-management for the
		    given vserver. 'Externalize' means that package metadata
		    and management tools (apt-get,rpm) are living in the host,
		    while 'internalize' means that data and programs from the
		    vserver will be used.
    hashify
                ... hashify the guest.
