-=head1 NAME
-
-pct - Tool to manage Linux Containers (LXC) on Proxmox VE
-
-=head1 SYNOPSIS
-
-=include synopsis
-
-=head1 DESCRIPTION
-
-pct is a tool to manages Linux Containers (LXC). You can create
-and destroy containers, and control execution
-(start/stop/suspend/resume). Besides that, you can use pct to set
-parameters in the associated config file, like network configuration or
-memory.
-
-=head1 EXAMPLES
-
-Create a container based on a Debian template
-(provided you downloaded the template via the webgui before)
-
-pct create 100 /var/lib/vz/template/cache/debian-8.0-standard_8.0-1_amd64.tar.gz
-Start a container
+ cpusets => [ __PACKAGE__, 'cpusets', []],
-pct start 100
-
-Start a login session via getty
-
-pct console 100
-
-Enter the lxc namespace and run a shell as root user
-
-pct enter 100
-
-Display the configuration
-
-pct config 100
-
-Add a network interface called eth0, bridged to the host bridge vmbr0,
-set the address and gateway, while it's running
-
-pct set 100 -net0 name=eth0,bridge=vmbr0,ip=192.168.15.147/24,gw=192.168.15.1
-
-Reduce the memory of the container to 512MB
-
-pct set -memory 512 100
-
-=head1 FILES
-
-/etc/pve/lxc/<vmid>.conf
-
-Configuration file for the container <vmid>
