Public bug reported: When using bridge networking under Ubuntu 12.04 LTS on HP C-Clase Blades (BL460c G7) which uses the be2net driver, networking doesn't work. Networking without bridging (assigning an address directly to, say, eth0) does work.
To recreate 1. Configure eth0 with an address 2. Test ping to other server on same network 3. Works Now take down the interface and configure bridging. 1. /etc/network/interfaces # Bridge between eth0 and eth1 auto br0 iface br0 inet static address 192.168.1.10 netmask 255.255.255.0 network 192.168.1.0 gateway 192.168.1.1 pre-up ip link set eth0 down pre-up brctl addbr br0 pre-up brctl addif br0 eth0 pre-up ip addr flush dev eth0 post-down ip link set eth0 down post-down ip link set br0 down post-down brctl delif br0 eth0 post-down brctl delbr br0 2. Bring br0 up 3. Ping other server on network 4.
