Soren is indeed correct, this does work - however you also need to setup
the guest to present a console to serial [0].  KVM's tty is displayed as
a VNC display, and Xen's is a pty.  However, a serial console is
arguably as good - and I quite like having the ability to have
ssh->serial console, and the ability to VNC. You can use "screen" as a
serial console client with "$ screen /dev/pts/3" (or whatever the serial
is present as in your host).
