Use the vmlinux.  By the way, if you strip it and maybe gzip it, it comes down 
to a much less unwieldy size.

That ought to at least be loadable by the domain builder, which is a start.  
Then we could see where it crashes next :-)  Have you managed to get it this 
far?  If so, what happened?

:-(

You might be able to get the unmodified_drivers stuff to work so that you get 
PV drivers under HVM.  I'm not sure if that supports 2.6.24 kernels yet 
though...  That'd improve performance a bit once it does work.

Cheers,
