You could also get the xen 3.4.0 hypervisor/tools RPMs from rawhide..
although from that xen-3.4-testing.hg repo you'll get 3.4.1-rc6 atm with a
lot of fixes after 3.4.0.

(I think the plan was to upload xen 3.4.1 to F11, later when it has been released
upstream.)

Modify your grub.conf to boot the xen hypervisor, add line /etc/fstab to
mount xenfs and hmm.. I guess that's it :)

See: http://wiki.xensource.com/xenwiki/XenParavirtOps
Pasting from that page:

Working example grub.conf with VGA text console:

title        Xen 3.4-unstable, kernel 2.6.30-rc3-tip
root         (hd0,0)
kernel        /boot/xen-3.4-unstable.gz dom0_mem=512M
module        /boot/vmlinuz-2.6.30-rc3-tip root=/dev/sda1 ro
module        /boot/initrd.img-2.6.30-rc3-tip
