And that guest is consuming 100% CPU? According to the stack trace it's idle...
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? Or are all your hosts identical (as is generally recommended)?
When it comes to software and configuration (apart from the obvious stuff), all my Xen hosts are identical - OpenSuSE 11.4 x86_64. 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.
