I think it's a known limitation. I remember running into it very long
ago. Anyways, gdbsx is now merged into xen. It can be used to debug any
guests. Please try it out: tools/debugger/gdbsx/README. You'd have to
build hypervisor with gdbsx support first, make gdbsx=y, and boot with
it.

Please cc me in followups as I'm not subscribed to this list.

thanks,
