[Xen-users] Dom0 cannot see network when bridge is enabled

[Ian Duggan <ian@xxxxxxxxxxxxx>]

I've seen a lot of threads w/ similar problems, but none have posted a
resolution.

I am using Debian 4.0r1 (Etch). I was using the xen packages from
stable, but have tried w/ testing as well and the problem persists.

Host is 10.0.0.20 on network 10.0.0.0/24.

Dom0 is thus 10.0.0.20

DomU is 10.0.0.30

When the bridge is enabled, DomU can ping everything. Everything can
ping DomU.

Dom0 can only ping DomU and itself. It can't see the 10.0.0.0/24 network
or anything beyond.

tcpdumps have not shown any ICMP traffic on any of the interfaces I can
see from within the Dom0, and machines in 10.0.0.0/24 being pinged from
the Dom0 see nothing either.

I'm trying to work out how it's supposed to work. It looks like the
bridge works by binding all the interfaces together via a common mac
address, is this correct?

How then, do peth0 and eth0 see each other's traffic?
