Well maybe I wasn't clear enough I didn't think that  would work but
once you have rhn-virtualization-host installed you can manually
create the VM inside the VM using the command line tools and use the
ISO image for the initial boot of the nested VM, but I wouldn't expect
it to be initially provisionable via the spacewalk GUI. keep in mind
nested VM's are a relatively new concept and not that many people
outside of VMWare ESXi users are using them so I doubt any one thought
of it (It may not have even been possible at the time) when that
portion of spacewalk was written.
I think if you need this feature you will need to create an RFE
(Request For Enhancement) for it in the spacewalks Bugzilla site.
