hi, when we want to setup a bridge without a ip address, function do_ifup will not activate the bridge. Eg. # ifconfig eth1 eth1 Link encap:Ethernet HWaddr 00:19:B9:41:2C:B9 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5096 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:395457 (386.1 KiB) TX bytes:0 (0.0 b) Interrupt:16 # ./network-bridge start netdev=eth1 bridge=xenbr1 will leave xenbr1 inactive. We should make the bridge active, then vif-bridge can work on the bridge.
