I followed the instructions in http://docs.openstack.org/liberty/networking-guide/scenario-provider-ovs.html (http://docs.openstack.org/liberty/net...). I finished the configurations and create a provider network as it said. However, I cannot ping the instance from either of the controller or the computer host. Anybody have met this problem?

Basically, VM-to-VM communication should work when all VMs sit on the same provider network. However, it is not straightforward to make a host or a controller to be able to ping a VM via the provider network. I'm not sure why you need to ping VM from your physical nodes in OpenStack.

Here is a list of check points, not limited.

  1. Check out if your controller node also has the provider network connection. Your physical node should have a routable path to the provider network or owns an IP address from the provider network's IP range.
  2. Double-check firewall rules of the provider network. Some firewall rules may have a dropping rule for ICMP (i.e., ping).
  3. Security Group: some default SG does not allow ICMP. You need to enable the ICMP rule for your VM.

Good luck,

Hi, My requirement is to allow my VMs on same node/different nodes to able to communicate with each other when they are talking over VLAN network. I mentioned provider network because that is the link I got on the net which mentioned something about vlan over open stack.
