vz - global OpenVZ configuration file

/etc/vz/vz.conf

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.

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=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).

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

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.

vzctl(8), vps.conf(5).
