5 | Subject: [Libvir] [PATCH] Linux-VServer support | |
6 | Date: Wed, 9 Jan 2008 22:51:20 +0100 (CET) | |
7 | ||
8 | This patch implements support for Linux-VServer guests. It is currently | |
9 | missing vcpu and console support, and the necessary virsh code to support | |
10 | it, but is otherwise pretty feature complete. | |
11 | ||
12 | This is an XML dump from one of my guests: | |
