This is an update of the patch http://www.redhat.com/archives/libvir-list/2008-October/msg00326.html To enable bridge support in the OpenVZ driver. As well as the fixes suggested last time, it includes an initial bit of HTML doc for the openvz driver, covering example XML, and the bridge configuration requirements Daniel diff -r 34eb1c9bdd7c docs/drvopenvz.html --- a/docs/drvopenvz.html Mon Nov 10 11:02:51 2008 +0000 +++ b/docs/drvopenvz.html Mon Nov 10 12:08:30 2008 +0000 @@ -122,6 +122,93 @@ </div> <div id="content"> <h1>OpenVZ container driver</h1> + <p> + The OpenVZ driver for libvirt allows use and management of container + based virtualization on a Linux host OS.
