Hi,
I am trying to perform a live xen migration and in the xm list it's saying
that it transfers but when I try and console onto the node it looks like it
does a kernel dump.
Here is my xend.log:

Any help would be appreciated. Both distros are running FC5. Does the same
hardware, kernel and image need to exist on the host and the migration
destination?
Thanks,
