SL4 can then run as a domU, with some caveats (cannot mix 32/64 bit

I'm not sure about that. I run 64-bit Fedora 8 on Intel, and run
several 32-bit guests.
Sorry - I was unclear and perhaps wrong. As stated on
http://www.linuxtopia.org/online_books/centos5/centos_5_xen_virtualization/centos5_ch-virt-hw-support.html
With Red Hat Virtualization, 32-bit hosts runs only 32-bit
paravirtual guests. 64-bit hosts runs only 64-bit paravirtual guests.
And a 64-bit full virtualization host runs 32-bit, 32-bit PAE, or
64-bit guests. A 32-bit full virtualization host runs both PAE and
non-PAE full virtualization guests.
This could have changed with 5.1 - Red Hat claims on
http://www.europe.redhat.com/rhel/virtualization/ that 5.1 now has
# The ability to run 32-bit para-virtualized guests on x86-64 systems
running in 64-bit mode.
(I guess they are talking about the dom0 here)
Well, I did mention my experience is on F8:-) I've only one system with
hardware virtualisation, and its first level OS is Fedora 8.
I use it to answer questions such as "Can I take this windows system run
it on different hardware without it barfing because it's become
unactivated?" and to similarly play with Windows domains.
I seem to have an inordinate array of problems:-( Fortunately, Fedora
has two virtualisation technologies, there's also KVM, and sometimes one
works when the other does not.
