rsync/scp as a copy method
* Stop most services on a machine to be migrated. “Most” means services such as web server, databases and the like — so you will not loose your data. Just leave the bare minimum (including ssh).
* Copy all your data from the machine to an OpenVZ box. Say you'll be using VE with ID of 123, then all the data should be placed to <code>/vz/private/123/</code> directory (so there will be directories such as <code>/vz/private/123/bin</code>, <code>etc</code>, <code>var</code> and so on). This could be done by scp or rsync.
* Set some VE parameters. You have to add <code>OSTEMPLATE=xxx</code> line to <code>/etc/vz/conf/123.conf</code> file, where <code>xxx</code> would be distribution name (like <code>debian-3.0</code>) for vzctl to be able to make changes specific for this distribution.
