NAME
       vz.conf - global OpenVZ configuration file

SYNOPSIS
       /etc/vz/vz.conf

DESCRIPTION
       This is the global configuration file for OpenVZ.  It consists of lines
       in the form

       PARAMETER="value"

       All parameter names and values are case-sensitive.  Quotes surrounding
       value are required if value contains spaces, and are optional
       otherwise. Extra spaces are not allowed. All unrecognized lines will be
       ignored.


   Global parameters
       VIRTUOZZO=yes|no
              This parameter can be set to yes or no, and used by the vz init
              script. In case it is not set to yes, nothing will be done to
              boot up OpenVZ on this node.

       LOCKDIR=directory
              Set the directory to put lock files to.

       VE0CPUUNITS=number
              Value of this parameter sets cpuunits for CT0 (host system).

       LOGGING=yes|no
              Enables or disables logging. This parameter can be set to yes or
              no, default is yes.

       LOGFILE=file
              Set location of log file, default is /var/log/vzctl.log.

       LOG_LEVEL=number
              Set the logging level for the log file (does not affect console
              output).  The greater the number is, the more information will
              be logged to the LOGFILE. Default is 0, which means to log
              normal messages and errors. If set to -1, only errors will be
              logged.

       VERBOSE=number
              Set the logging level for console/terminal output (does not
              affect log file).  Default is 0, which means to log normal
              messages and errors.  Increasing the number makes vzctl(8) more
              verbose.

       MODULES_DISABLED=yes|no
              If the value of this parameter is set to yes, no attempt to load
              kernel modules is made by the vz initscript. This is helpful on
              systems which have OpenVZ-specific features compiled into the
              kernel (i. e. not as modules).

       IPTABLES_MODULES="module module ..."
              List of iptables kernel modules to be loaded by vz initscript
              before loading OpenVZ modules (which is required for iptables to
              work inside containers). If not set, value of IPTABLES is used.

       VZFASTBOOT=yes|no
              If the value of this parameter is set to yes, vz initscript
              called with start argument will start the containers with
              uncleanly shutdown quota state without performing quota
              reinitialization (which is usually a time-consuming process).
              After all the containers are started, the initscript when
              restarts those containers with unclean quota in a normal way (to
              recalculate/fix quotas).

       TEMPLATE=directory
              Value of this parameter is a directory in which all container
              template data are stored.


   Network interface parameters
       VE_ROUTE_SRC_DEV="device"
              This parameter specifies the network device name which IP
              address will be used as the source IP. This is helpful in case
              more than one network interface is configured on HN and there is
              a need to specify the source IP address. Default is the first
              device in the network device list.

       NEIGHBOUR_DEVS="detect"
              Controls on which interfaces to add/remove ARP records for a
              container IP, also which interfaces to use to query/announce
              ARP. If this is set to detect, the right network interface (the
              one which is in the same subnet as a CT IP) will be chosen
              automatically. Any other value restores old (as of vzctl 3.0.19
              or older) behavior, when all the possible interfaces were used.

       ERROR_ON_ARPFAIL=yes|no
              In case the value of this parameter is set to yes, vzctl will
              fail to start a container if there is another host with the same
              IP in the subnet.  The value of no makes vzctl to only print the
              warning.


   Defaults for containers
       Below parameters are defaults for containers, and can be overwritten by
       parameters in ctid.conf(5) per-container configuration file.

       DISK_QUOTA=yes|no
              In case the value of this parameter is set to no, all disk quota
              operations are disabled.

       VE_ROOT=directory
              Value of this parameter is the directory which serves as
              container root mount point. Value must contain literal string
              $VEID, which will be substituted with the actual numeric CT ID.

       VE_PRIVATE=directory
              Value of this parameter is the directory in which all the files
              and directories specific to that container are stored. Value
              must contain literal string $VEID, which will be substituted
              with the actual numeric CT ID.

       CONFIGFILE=name
              Default configuration file for create action, corresponds to
              --config option.

       IPTABLES="module module ..."
              List of iptables modules to be enabled for containers,
              corresponds to --iptables option.

       Most of the other parameters that appear in per-container configuration
       files ctid.conf(5) can be also set here. Still, it is recommended to
       keep TEMPLATE, VE_PRIVATE and VE_ROOT in this configuration file, and
       all the other container related parameters in per-container
       configuration files.
