Could you run "xm info" on both and post the output? I suspect it's the difference in the hardware capabilities between the boxes.

I'm having problems getting the migration from one machine to
another. When I start the migration, it run for probably 15 seconds
and ends, and the virtual machines dies. Here's my setup, 2 xen host
running centos 5.1, xen-3.0.3-41.el5_1.6, and kernel
2.6.18-53.1.21.el5xen. Server01 has a VM called vm01 and I'm trying
to migrate that over to server02. Server02 has an NFS mount to the
directory on server01 that holds the virtual machine disk. Any
ideas, is it my hardware?
