[Xen-users] Xen 3.0 networking trouble with eth1
Hello, all!
I have a Xen 3.0 setup on a server with two network cards, which are supposed
to work in two totally independent virtual nets using bridging. Now, the first
virtual net works as a charm, connecting several domUs.
The problem is that with the second NIC (eth1) there's no luck at all -
everything is exactly the same, virtual infrastructure seems to be up and
running, packets get through to domU just fine (visible with tcpdump on domU),
but no packets ever get back to dom0. IP communication through the physical
interface works in both directions w/o any trouble.
In other words, it's just like my virtual crossover cable dom0 <-> domU is half
broken, and just on second virtual network.
Has anyone ever experienced the same problem, or does anyone have an idea what
might be wrong with this setup?
Here are some details:
