FYI, I have just installed a Fedora 12 x86_64 guest on a Fedora 11 x86_64 
KVM host using

virt-install --hvm \
 --location http://download.fedora.redhat.com/pub/fedora/linux/development/x86_64/os/ \
 --name f12x86_64xen --ram 800 --accelerate --noautoconsole  \
 --file /dev/HostVG/f12x86_64xen --vnc


Once installed, I installed the Xen dom0 kernel from fp.org/~myoung/dom0/
re-configured grub, and successfully rebooted into a Xen Dom0, and was 
able to create paravirt guests successfully. Most of the libvirt-TCK test
suite passed, and the only bugs look trivial to solve in libvirt's Xen
driver. 

So for that environment at least, the Dom0 kernels are looking pretty
good when used with F12 and the libvirt Xen driver is still functioning 
reasonably well.

Regards,
Daniel
