[Fedora-xen] Problem installing a para 32 bit FC5 guest on a 32 bit FC7 domU

I''m trying to install a 32 bit FC5 paravirt guest on a 32 bit FC7 domU
and
I''m getting the following error:

libvir: Xen Daemon error : POST operation failed: (xend.err "Error creating
domain: (2, ''Invalid kernel'', ''xc_dom_compat_check:
guest type
xen-3.0-x86_32 not supported by xen kernel, sorry\\n'')")

Everything I read says this should work.  The hypervisor will allow me to
install a 32 bit FC7 guest fine.  The following is a cut and paste the
commands I''m actually putting in and their output;

[root@localhost ~]# virt-install --os-variant=fedora5 --name=dddev
--location=http://167.208.15.27/FC5/i386 -f /var/lib/xen/images/dddev.img -p
-r 3072 --vnc --vcpus=4

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

Fedora Core 5 was non-PAE,  Fedora Core 6 and later are PAE. You cannot run
non-PAE 32-bit guests on a PAE host, hence why the hypervisor is telling
you "guest type xen-3.0-x86_32 not supported by xen kernel"
