This guide will show you how to convert an OpenVZ (Proxmox) container to a
template. You can then use this template on any other OpenVZ (or proxmox) host.
This can be used either to migrate containers or to create a kind of master
image to deploy new hosts from.
This guide is tested on a proxmox machine running proxmox version 3.2.

Login as root to the proxmox machine via ssh.
Get a list of containers using `vzlist`:
CTID NPROC STATUS IP_ADDR HOSTNAME
100 85 running 10.21.21.5 master.raymii.nl
101 34 running 10.21.21.6 test-master.raymii.nl
I want to create a template of `master.raymii.nl` which has ID 100.
You must stop the container before creating the image:
vzctl stop 101
Stopping container ...
Container was stopped
Container is unmounted
Go to the container folder:
Then start the image creation:
tar -cvzpf /var/lib/vz/template/cache/master.raymii.nl.tar.gz .
This will place the image in
`/var/lib/vz/template/cache/master.raymii.nl.tar.gz`. This file can be copied
and deployed on another host, or used on the same host as a template.
