Hi, everyone,I have installed open vswitch according to INSTALL.Linux on Ubuntu
Oneiric. And the open vswitch is in userspace. I have typed the commands in
following steps:
ovs-vsctl --no-wait init
ovs-vswitchd --pidfile --detach --logfile
ovs-vsctl add-br br0
ovs-vsctl set bridge br0 datapath_type=netdev
ovs-vsctl add-port br0 eth0
ovs-vsctl add-port br0 eth1
ovs-vsctl add-port br0 eth2
After that, I have checked the log file under
/usr/local/var/log/openvswitch/ovs-vswitchd.log, got:

So it seems that I failed on this little attempt. Is there steps or
requirements I have missed? I have installed all the softwares required for a
userspace program of Open vSwitch. And how to run a simple demo with Open
vSwitch?Hope make myself clear.
Cheer,
