I just realised that the monitor operation requires the same start delay
as the "start" operation otherwise HA will complain obviously...

That's part I'd like some advice about. I found Xen agent working with
"migrate_from" and "migrate_to" operations? 

Which one would I need to use for instance if I wanted to move ~15VMs to
the other node in a 2 node cluster by putting one node into standby? 

I want the cluster NOT to move all at the same time because some of them
would crash due to the load but one by one they work always...
