vserver(8) The vserver utility enables you to manage the state of vservers, including building, starting, stopping, etc.


vserver [-s|--sync] [-v|--verbose] [--silent] [--] vserver command [--help] args*
--sync - Perform synchronization with vshelper to ensure that the guest has been stopped
--verbose - Makes things a lot louder.
--silent - Removes most informative messages.
vserver - The name of a vserver.
command - One of the commands listed below.
provides additional help for provided command, for example: vserver - build --help args are the arguments that are possible for the different commands, see the arguments for each command listed below


start [--rescue [--rescue-init] program args]
Starts the specified vserver. The optional argument --rescue starts the vserver in rescue mode, which runs program args* to start the vserver instead of whatever is configured. The optional argument --rescue-init makes the command appear as PID 1 in the vserver. This can be used to start /bin/bash to investigate why a vserver is not able to start correctly.
stop [--rescue-init]
Stops the specified vserver, and kills the remaining processes. The optional argument --rescue-init can be used to stop a vserver that was started with the option of the same name.
Restarts the specified vserver. This is the subsequent execution of a synchronized 'stop' and a 'start'.
Restarts a running vserver.
suexec user program args*
Executes program args* as the specified user in the vserver.
exec program args*
Executes program args* as the root user in the vserver.
Executes the configured shell (default: /bin/bash if it exists) in the vserver and allocates a pty.
chkconfig chkconfig-options*
Modifies the init-system; currently, only Red Hat's chkconfig is supported.
Returns an exit code of 0 iff the vserver is running, 1 if not.
Provides some human readable status information about the vserver, and succeeds iff the vserver is running.
build buildopts*
Create a vserver from scratch, where the buildopts* are a set of options and a build method. As this option calls vserver-build, please see vserver-build(8) for a complete listing of possible options and methods.
Remove a vserver.
unify [-R] [vunify-opts*]
Unify or de-unify the vserver with its reference vserver(s).
pkg install pkg*
Installs package(s) pkg 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 the vserver.
