----- Original Message ----- From: "Greg Brackley" <lists-xen-devel@xxxxxxxxxxxxxxxxxxxx> dom0: fake eth0 -> vif0.0 --- br0 --- bond0.1 (VLAN 1) --+ | +------------------------------------------------------+ | | + -> real eth0 -> the network +--- bond0 -+ +--> real eth1 -> the network I seem to be going backwards on the networking. I can't get the networking operating for a dom0 only machine, using FC4 init scripts only. The setup is two physical ethernets (sk-9e22), with bond, a single vlan, a single bridge, and a single vif/veth0. I have added another ethernet card so that I can SSH in (eth2/eth3), and put an IP address directly on eth2 (this works). The eth2 interface should be outside the problem. I can reliably ping (ICMP) the veth0 interface from other networks. UDP and TCP appear to be broken. e.g. DNS fails. SSH fails. I have tried turning ARP off on all interfaces except veth0, but that alone didn't help. I wonder if it is some checksum issue with the sk98lin driver? I might try using the e1000 card as the eth0/eth1 interface. I have a tg3 based machine working ok with a single VLAN. Very weird (which means I probably don't understand something). Lots of info below.
