### Open vswitch problem

Hi I am testing openstack with my personal laptop. I install it in Centos 7. I installed packstack and then openstack. But I found there is no open vswitch installed. So I install it separately and after that, I type ovs-vsctl show´ commend and it showed nothing meaning that there is no bridge built. So , do I have to build bridge integration, bridge provider, and bridge tunnel ? If so, how to build them. Please guide me.
