This looks pretty promising and of course I had to try it immediately.
If I understand the documentation right you have to add an 
xen_shell="username" to the domU configuration to allow a user to control 
this domU.

I did so and then launched xen-shell (or xen-login-shell) however the shell 
gives me some errors (doesn't understand most of the commands):

xen-shell v1.1.80 - type 'help' for help.
xen-shell> help
xen-shell v1.1.80

The following commands are available within this shell:

      boot - Boot the Xen guest.
   console - Gain access to a Xen guest via the serial console.
      exit - Exit the shell.
      help - Show general, or command-specific, help information.
    passwd - Change the password used to access this host.
      quit - Exit this shell.
    reboot - Reboot the Xen guest.
    serial - Gain access to the Xen guest via the serial console.
  shutdown - Shutdown the Xen guest.
    status - Show the status of the Xen guest.
       top - Show system resource usage.
    uptime - Show the uptime information of your guest system and this host.
   version - Show the version of this shell, and of Xen.

For command-specific help run "help command".

xen-shell> list
Unknown command: 'list' - type 'help' for help.
xen-shell> boot

  You have no selected a Xen instance to control, and this command
 applies to only one instance rather than all of them.

  You may use the following two commands:

    list    ->  Show which Xen instances you may control.

    control ->  Take control of the specified Xen instance.

If i use the 'top' command I get a list of all running domUs (when running the 
shell as root).
