[sles-beta] Creating XEN VM files to use with HA cluster

[Darren Thompson]

Team

OK I now have managed to create a cluster XEN VM (using a OCFS2 shared
file-system and the notes from my previous correspondence).

It looks like the 'live migration/relocation' function is now managed by
'lib-virt' and not xend (there is no xend-config.sxp file for example).

Is there any notes on the configuration steps required for 'live
migration/relocation' now, the YAST2 'relocation server' module does not
seem to do anything and it's setting do not "stick".
