[Xen-users] xen bridge config problem
I am unable to ping the rest of the machines on the network from the guest OS.
The host, Domain-0 (10.0.1.201), and guest 10.0.1.209 can ping each other.
The host, Domain-0 (10.0.1.201) can ping the gateway 10.0.1.1.
The guest 10.0.1.209 can not ping the gateway.
I want guest domains to be available from the network. Any tips what I might
be missing? See config details below.
Thanks,
Todd
