Possible to install Fedora Rawhide (F12) on RHEL5?

[Orion Poplawski]

I'm trying to install current Fedora Rawhide on my RHEL5 box -

Domain installation may not have been
  successful.  If it was, you can restart your domain
  by running 'virsh start xenfdev64'; otherwise, please
  restart your installation.

Any hope?

For anyone interested:

  Okay, so it turns out the problem is

    # CONFIG_KERNEL_GZIP is not set
    # CONFIG_KERNEL_BZIP2 is not set
    CONFIG_KERNEL_LZMA=y

  the change was introduced by:

    * Mon Jul 06 2009 Chuck Ebbert <cebbert(a)redhat.com&gt;
    - Use LZMA for kernel compression on X86.

  Xen's bzImage loaded can only handle compressed gzip, not compressed 
  LZMA

  Switching to LZMA means that Fedora kernels cannot be booted by any   
  deployed or upstream versions of Xen; we really should switch this
  back to gzip

Cheers,
Mark.
