NAME[edit]

vzsplit − generate a sample container configuration file

SYNOPSIS[edit]

vzsplit

[-n numve] [-f conf_name] [-s swapsize] [-v yes|no]

DESCRIPTION[edit]

The vzsplit utility is used to split the Hardware Node into equal parts. It generates a full set of system resource control parameters for the given number of containers. The values are calculated from the total physical memory of the Hardware Node the utility runs on, and the number of containers the Hardware Node shall be able to run even if the given number of containers consume all the resources available.

Without any option given, vzsplit prompts for the desired number of containers and outputs the resulting resource control parameters to stdout.

If there are not enough system resources to run the specified number of containers, an appropriate message is shown and the sample configuration file is not generated.

OPTIONS[edit]

-n numve

Specify the number of containers.

-f conf_name

Specify the configuration sample name to write configuration to, instead of standard output. The file created will be named /etc/vz/conf/ve-conf_name.conf-sample.

-s swapsize

Specify the swap size in Kbytes. If this option is not given, the swap size is read from /proc/meminfo.

-v yes|no

Whether to generate VSwap enabled configuration. Default is auto-detect by checking if running kernel is VSwap capable; this option overrides auto-detection.

EXIT STATUS[edit]

vzsplit returns 0 upon a successful execution. If anything goes wrong, it returns 1.

SEE ALSO[edit]

ctid.conf(5).
