Hmm.. good question. I don't know, it's always done for me here. One
option would be to just download OVM from edelivery.oracle.com, it's
free, and should ahve both binary and sources. You could look at spec
file to see how they do it.

To debug hypervisor, you'll need kdb. You could get that from OVM (xen
3.1.4) also, or http://xenbits.xensource.com/ext/debuggers.hg  for
unstable. See README-dbg. If you put earlykdb in xen kernel line in
grub.conf, it would break into kdb during boot very early. Then you can
single step, set breakpoints, etc...
