I installed openstack juno on centos7.

Then I updated centos7, using yum update.

Now when I restart centos7, I'm not able to ping any other computer on same network. (Earlier I was able to ping). Packet is not going outside my computer.

openvswitch status is "running". But when I restart openvswitch everything starts working. The openvswitch status is still remains "running" after restart.

Can someone explain me what is the problem?
