This is likely to be a configuration issue and therefore would be more
appropriate for xen-users@ in the first instance. The xen-devel@ list
focusses on discussion of the development of Xen
http://wiki.xen.org/wiki/Asking_Xen_Devel_Questions. I have moved this
post to xen-users@ and put xen-devel@ to bcc.

If I were you I would start by checking my firewall configuration in
both dom0 and domU.

If this doesn't help then I suggest you include more details about the
specifics of your configuration, at a minimum all the networking related
stuff mentioned on http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen,
precise kernel versions for dom0 and domU, exact guest configuration and
whatever else you feel might be relevant.
