Did you first try running it under baremetal Linux (using a Live CD for
example?) Did it work there?

How does it not work? Can you program it? Is this under a guest or the
main kernel? When it wsa not working, did you try all the debug
options enable (http://wiki.xen.org/wiki/XenSerialConsole) to
 see if there is anthing being reported?
