[Pacemaker] Xen on two node DRBD cluster with Pacemaker

[Bart Coninckx]

Hi all,

could somebody point me to what is considered a sound way to offer Xen guests 
on a two node DRBD cluster in combination with Pacemaker? I prefer block 
devices over images for the DomU's. I understand that for live migration DRBD 
8.3 is needed, but I'm not sure as to what kind of resource 
agents/technologies are advised (LVM,cLVM, ...) and what kind of DRBD config 
(seperate devices for each DomU I guess?)


Thank you!


Bart
