Okay, that is the error I get. I googled around, but no one seems to
have my exact problem (and their solutions do not work for me.) I have
a stock Debian 4.0 setup, apt-get Xen 3.0, etc ... Now, I setup a
Dom1, and I run a webserver on Dom1 on port 80.

In Xen, my networking is (network-script network-nat) (vlf-script vlf-nat)

I setup iptables to -p tcp --dport 80 -d Dom0's_ip_address -j REDIRECT

where iss the ip address of Dom1 (from the view of Dom0; i.e.
on Dom0, if I do "wget", I get the webpage from Dom1)

Then, dmesg gives me the error mentioned above.

So I look around, and I see that according to /sbin;ifconfig the vif
correpsonding to my Dom1 is actually ... so I try that, but
no tluck either.
