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? -- Vedsar Kushwaha M.Tech-Computational Science Indian Institute of Science
