I have a question concerning the workings of networking in 
qemu/kvm+libvirt -- my apologies in advance if this is the wrong mailing 
list for such a question.

I have a host machine with which I'm trying to redirect network traffic 
coming from a guest's NIC to a different IP.  There is a bridged adapter 
on the host (without an IP configured on it) that is used by my guest's 
NIC -- the IP, etc. is configured within the guest.  From what I can 
tell, the traffic is not traversing iptables on the host, BUT I can see 
traffic leaving the guest's NIC (on the host) using tcpdump.  I've gone 
as far as logging all traffic on the vm's NIC (on the host) using 
iptables just to confirm that the host's iptables is not seeing the 
traffic.

I'm wondering, is this the expected behavior?  And if so, how then can 
redirect specific traffic from the guest (transparently) to a different 
IP?
