That's pretty peculiar, Bryan.  We're having problems with the network
configuration scripts at the moment, but it looks to me like your network is
intact.  If the packet has reached vif1.1, then it really ought to reach the
domU, because that is a pretty simple connection, and well tested.  Do you
have any firewalling / iptables rules set up in the guest domain?  Can it
receive pings from elsewhere on the network?  If it's not firewall rules, I'm
flummoxed, and you ought to file a bug.

Cheers,

Ewan.
