Hi, Horms

This patch focus only manually dumping domU's core.
How can I use the panic option of xen-console?
I thought your patch to panic xen.
Can I dump domU's core with the option?

>Also, is this option really Xen specific. It seems it

This is a patch to dump domU's core,
so Linux is not useful becaus Linux can dump by calling crash_kexec().
