hello, I have build a 2 node devstack environment with ovn enabled by following http://docs.openstack.org/developer/networking-ovn/testing.html with 2 physical machine on one blade server.
Then I created 3 instances, one in the controller node and other two in the compute node, same as : http://galsagie.github.io/sdn/openstack/ovs/2015/05/30/ovn-deep-dive The issue I met is : the 2 instances on the compute node can not get IP address from DHCP. Then, I give the 2 instances on the compute node with IP addresses by hand, and they can reach each other. I guess it could be caused by MTU setting. so, I changed my physical nic interface MTU to 9000. => Still not work. :( Anyone can help me ? Thanks. -chen
