| .TH vz.conf 5 "10 Dec 2009" "OpenVZ" "Containers" |
| .SH NAME |
| vz.conf \- global OpenVZ configuration file |
| .SH SYNOPSIS |
| /etc/vz/vz.conf |
| .SH DESCRIPTION |
| This is global configuration file for OpenVZ. |
| It consists of lines in the form |
| .PP |
| \fBPARAMETER\fR="\fIvalue\fR" |
| .PP |
| All parameter names and values are case-sensitive. |
| Quotes surrounding \fIvalue\fR are required if value contains spaces, and |
| are optional otherwise. Extra spaces are not allowed. All unrecognized lines |
| will be ignored. |
| .SS Global parameters |
| .IP \fBVIRTUOZZO\fR=\fByes\fR|\fBno\fR |
| This parameter can be set to \fByes\fR or \fBno\fR, and used by |
| \f(CW/etc/init.d/vz\fR script. In case it is not |
| set to \fByes\fR, nothing will be done to boot up OpenVZ on this node. |
| .IP "\fBLOCKDIR\fR=\fIdirectory\fR" |
| Set the directory to put lock files to. |
| .IP \fBVE0CPUUNITS\fR=\fInumber\fR |
| Value of this parameter sets \fBcpuunits\fR for CT0 (host system). |
| .IP "\fBLOGGING\fR=\fByes\fR|\fBno\fR" |
| Enables or disables logging. This parameter can be set to \fByes\fR or |
| \fBno\fR, default is \fByes\fR. |
| .IP \fBLOGFILE\fR=\fIfile\fR |
| Set location of log file, default is \f(CR/var/log/vzctl.log\fR. |
| .IP "\fBLOG_LEVEL\fR=\fInumber\fR" |
| Set the logging level. The more \fInumber\fR is, the more information will be |
| logged. |
| .IP "\fBVERBOSE\fR=\fInumber\fR" |
| Set the output verbosity. Default is 0. |
| .IP "\fBMODULES_DISABLED\fR=\fByes\fR|\fBno\fR |
| If the value of this parameter is set to \fByes\fR, 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). |
| .SS Disk quota parameters |
| .IP \fBDISK_QUOTA\fR=\fByes\fR|\fBno\fR |
| In case the value of this parameter is set to \fBno\fR, all disk |
| quota operations are disabled. |
| .IP \fBVZFASTBOOT\fR=\fByes\fR|\fBno\fR |
| This parameter is used by \f(CR/etc/init.d/vz start\fR script. In case the value |
| of this parameter is set to \fByes\fR, 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). |
| .SS Network interface parameters |
| .IP \fBVE_ROUTE_SRC_DEV\fR="\fIdevice\fR" |
| 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. |
| .IP \fBNEIGHBOUR_DEVS\fR[="\fBdetect\fR"] |
| 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 \fBdetect\fR, |
| 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. |
| .IP \fBERROR_ON_ARPFAIL\fR=\fByes\fR|\fBno\fR |
| In case the value of this parameter is set to \fByes\fR, vzctl will fail to |
| start a container if there is another host with the same IP in the subnet. |
| The value of \fBno\fR makes vzctl to only print the warning. |
| .IP \fBTEMPLATE\fR=\fIdirectory\fR |
| Value of this parameter is a directory in which all container template data are |
| stored. |
| .SS Defaults for containers |
| Below parameters are defaults for containers, and can be overwritten by |
| parameters in \fBvps.conf\fR(5) per-container configuration file. |
| .IP \fBVE_ROOT\fR=\fIdirectory\fR |
| Value of this parameter is the \fIdirectory\fR which serves as container root |
| mount point. Value must contain literal string \fB$VEID\fR, which will be |
| substituted with the actual numeric CT ID. |
| .IP \fBVE_PRIVATE\fR=\fIdirectory\fR |
| Value of this parameter is the \fIdirectory\fR in which all the |
| files and directories specific to that container are stored. Value must contain |
| literal string \fB$VEID\fR, which will be substituted with the actual |
| numeric CT ID. |
| .IP \fBCONFIGFILE\fR=\fIname\fR |
| Specified default configuration file on \fBcreate\fR action, corresponds to |
| \fB--config\fR option. |
| .PP |
| Most of the other parameters that appear in per-container configuration files |
| \fBvps.conf\fR(5) can be also set here. Still, it is recommended to keep |
| \fBTEMPLATE\fR, \fBVE_PRIVATE\fR and \fBVE_ROOT\fR in this configuration |
| file, and all the other container related parameters in per-container |
| configuration files. |
