Serial port is (usually) assigned to Xen + Dom0. You can however use
xencons to debug your DomU.
Gerd Hoffman's XenSummit presentation is a good resource to learn about xencons:
http://xen.xensource.com/files/xensummit_4/xensummit_linux_console_slides.pdf

In my DomU config files I have:
extra = "console=xvc0 xencons=xvc"
This should be enough to get you started.
