Usually it's best to generate the initrd image in the guest,
and use the distro provided domU kernel.
If you install the guest using the guest distro installer it'll do it for you
automatically.
You can also do it from dom0.. example for centos/rhel/fedora:
mkinitrd -v -f --with-module=xenblk --with-module=xennet
/boot/initrd-domU-version.img <kernelversion>
