Xen is only a hypervisor, and "normally", people run an OS inside it - you can look at the "mini-os" in the xen sources to see a minimal OS, but without any os as guest, you have no devices, no IO, nothing. xen has mutliple schedulers, and playing with their options can have many effects in terms of "real-time-ness". But, if you run an OS inside Xen, you have to configure Xen and the guest OS, and maybe the host OS, which hists the drivers, correctly to get real time features. This can probably be done, but it seems to be more complex than just running a Linux modfied/configured for realtime use.
