Did you edit grub.conf to allow the kernel to boot via the hypervisor? That kernel doesn't do it for you. You want something along the lines of

Title something
       root (hd?,?)
       kernel /xen.gz or /boot/xen.gz
       module /vmlinuz-something kernel_boot_args
       module /initramfs-something

adjusted to match your boot environment as given by the other grub entries.
