Can ping to dhcp server from controller nodes but not from compute nodes.

Hi,

Each node has two NIC: 1Gb Eth (eth0), Infiniband (ib0). By following the installation tutorials (http://docs.openstack.org/liberty/install-guide-ubuntu), I set up a controller node and two compute nodes.

I can run two nova instances with provider network with eth0 interface. There is no problem.

But I have some problems in deploying provider network with ib0 interface. I found two weird behaviors related with it.

  1. No node can ping to VMs attached to ib0 interface.
  2. Controlloer node can ping to the dhcp agent server running on the controller node, but the other compute nodes cannot ping to it.

Thanks for any information.
