looking very good!!!
@r1 our complete setup:
[FreeNAS NFS] <----shared-storage----> [Pool of 2 servers (xen22 + xen23)] ----XAPI---> [XO from sources] -----remote----> [FreeNAS NFS]
All [servers] are real hardware servers, no VMs involved.
Same chain of servers for xen19, execpt there are more pool members (and VMs).
@stormi I'm not complete sure if I did the iso upgrade or not... 
But it's a good idea to reinstall the poolmaster from scratch...
