Also, I used to re-create the HYPERVISOR_console_write syscall, and configure Xen to allow unpriv domains to write to the serial console. I think the new HYPERVISOR_console_io syscall can be convinced to do the same thing. In my xen tarball at http://www.diku.dk/~jacobg/self-migration/ you can find the source of 'mstrap' which is very much like mini-os, but perhaps a little more up to date. The network driver is not working in Xen2, but the elf-image should at least load using the recent tools.
