NAME
       vz - global OpenVZ configuration file

SYNOPSIS
       /etc/vz/vz.conf

DESCRIPTION
       This is 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
              /etc/init.d/vz 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. The more number is, the more information
              will be logged.

       VERBOSE=number
              Set the output verbosity. Default is 0.

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

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

       VZFASTBOOT=yes|no
              This parameter is used by /etc/init.d/vz start script. In case
              the value of this parameter is set to yes, all containers with
              incorrectly shutdown quota state are started without quota
              check, and after all containers will be started, those marked
              containers are restarted (to fix quotas).

   Network interface parameters
       VE_ROUTE_SRC_DEV="device"
              This parameter specifies the network device name which ip
              address will used for source ip. If on HN configured > 1 network
              interfaces and needed to specify the source ip address, set
              corresponding device. By default takes the first in 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.

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

   Defaults for containers
       Below parameters are defaults for containers, and gets overwritten by
       parameters in vps.conf(5) container configuration file.

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

       CONFIGFILE=name
              Specified default configuration file on create action,
              corresponds to --config option.

       Any other parameter that appears in per-PE configuration file
       vps.conf(5) can be also set here. Still, it is recommended to keep
       TEMPLATE, VE_PRIVATE and VE_ROOT in this configuration files, and all
       the other container related parameters in per-container configuration
       files.
