Can you paste your xen_cmdline? If you don't have a serial console you should use console=vga in your xen_cmdline. Additionally if you have a usb debug port you could use that as console with console=dbgp [1]. > Does the xen kernel show some debug when booting?

Yes, Xen will print debug info while booting to the console specified in the "console" option, which can be the serial, VGA or USB debug port. They are not exclusive, you can send output to several different destinations at once. Roger. [1] http://xenbits.xenproject.org/docs/unstable/misc/xen-command-line.html
