Xen devel - Nov 2004 - Vif only accepts connex after talking out of domain.

My domains dont see any traffic until you try to connect out
from within the domain. Tried this several times and it was
consistent. I have no firewall either. running each domain 
on different cpu probably doesn''t help, although Im no 
network expert.


 Here is some info.
