I'm puzzled - before it would consume 100% CPU. Now it doesn't - even if I try it with the older DomU (11.2). I'll try to replicate the 100% CPU consumption tomorrow and get a trace of that. > Anyway, considering a recently analyzed problem, is this (mis)behavior > dependent on certain characteristics of the source/destination hosts, > or is it happening no matter between which you migrate?

I was running older OpenSuSE Dom0's before (11.2) and never got live migration to work properly - but I think there were different errors and issues. I also setup two additional hosts with updated Xen (11.4 with Xen 4.1.1 from Virtualization repository) but it was the same.
