On your original setup, I noticed you're using "root=LABEL=/1" on the
original grub stanza and "root=LABEL=/" on Xen stanza. Are they
supposed to refer to the same root? This could be one of things
causing you problems.

My guess is the kernel config you use is missing some essential
modules needed to boot correctly. Here's some of the things you can
try :
- Install RHEL's Xen. This should be pretty straightforward, you'd end
up with Xen 3.1+ and a working grub.conf stanza for Xen with RHEL's
kernel-xen
- Install Xen package from gitco (http://www.gitco.de/repo/). You can
get Xen 3.4.1 (currently in testing) but still using RHEL's kernel-xen
- If that works, you can simply compile another xen kernel as you
like, using either 2.6.18 or later pv_ops kernel. If using 2.6.18, you
can use RHEL's kernel-xen config as a base.
