BTW, it boots fine with vmlinuz, which is a CentOS xen kernel. However,
it goes right into some installation, which I can't seem to get out of.
Does it really matter which kernel I run? And how can I avoid the
installation menus.
I also just discovered that I boot fine with
vmlinuz-2.6.18-8.1.6.el5xen, but it pukes on mounting file systems.

Can you use virt-install to get pygrub set up, and that way you use a
grub and kernel from the Xen guest domain itself?
I've moved away from doiing that sort of "sda1", "sda2", "sda3"
filesystem allocation: I use "xvda" or "sda" so I can do more
synchronous snapshots, and use kpartx to get access to individual file
systems from Dom0.
