Okay I'm running debian sqeeze (testing) which bridge-utils 1.4-5 and
kernel 2.6.30 amd64 variant
This is running on a new Dell Poweredge R610 with dual dual bnx2 nics

I have a bridge I'm trying to create for kvm. eth0 is my local access
so it's just a now nic with dhcp connected to my lan, which works no
problem. Then I created a bridge called prot0 and set it to manual,
and added eth1 (also set to manual) to it. When I start my kvm guest
it creates a tap interface called vnet0 also without an ip and adds it
to the bridge. My guest OS then has eth0 which has an ip on static.
So at this point this is what things look like on the host box.
brctl show
bridge name bridge id STP enabled interfaces
prot0 8000.0022195e3239 no eth1
vnet0
brctl showmacs prot0
port no mac addr is local? ageing timer
1 00:22:19:5e:32:39 yes 0.00
2 ba:ea:0d:0f:8b:aa yes 0.00
on the guest I start a ping to anything, google.com for this example.
And I set tcpdump -i prot0 or vnet0 and I see the arp request for the
dns servers but no reply. Which looks like this.
09:54:43.444533 ARP, Request who-has dns1.domain.tld tell
rdns.guestdomain.tld, length 28
09:54:44.440585 ARP, Request who-has dns1.domain.tld tell
rdns.guestdomain.tld, length 28
09:54:45.440587 ARP, Request who-has dns1.domain.tld tell
rdns.guestdomain.tld, length 28
But if I do a tcpdump -i eth1 I see nothing at all.
here is my /etc/network/interfaces
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp
auto prot0
iface prot0 inet manual
bridge_ports eth1
bridge_stp off
bridge_maxwait 5
And my lsmod

I just don't understand how it can be getting to prot0 (my bridge) but
no be seen on eth1 which is a bridge member.
Any help or anything I can try would be most helpful, Thanks in advance.
