Do you have any logs of the error(s) when booting up? Can you show us the configuration of your Xen guest and it's LVM volumes, VG and PVs as well? The more details the better. I personally don't do Gentoo or Xen, so I can't help there. But I can ask you to post more details. A boot log would be very helpful.
