I am trying to install openvswitch on my ubuntu 12.04 Machine for KVM.

But it is showing

"Module has probably not been built for this kernel" 

tried "module-assistant auto-install openvswitch-datapath" which returned "

Version 1.4.0-1ubuntu1.5 of openvswitch-datapath-module-3.2.0-23-generic already installed, skipping.


kernel 3.2.0-23-generic, Ubuntu 12.04

lsmod|brcom showing nothing

How can i fix datapath module issue?


Remove default bridge

rmmod bridge

Enable Module brcompat

modprobe brcompat_mod


lsmod|grep brcompat

restart ovs

service openvswitch-switch start      

If everything is fine try adding interface
