My grub.conf is:

title Xen(2.6.31.13)
    root (hd0,10)
    kernel /boot/xen.gz console=com1,vga com1=9600,8n1
    module /boot/vmlinuz-2.6.31.13 root=/dev/sda1 ro nomodeset
    module /boot/initrd-2.6.31.13.img

Would you give me more suggestions. Thank you.

Best wishes.

Some other options: add noreboot to Xen command line and see if anything
else does get printed before reboot. And/or connect a serial line and have
Xen log to serial console and see if any other diagnostic messages are
visible from that.
