Hi list,
I'm working under Centos 6.4 + Havana.
I have three nodes working:
server node: running neutron-server
network node: running neutron-openvswitch-agent and neutron-dhcp-agent
compute node: running neutron-openvswitch-agent
I created a gre network and booted a instance successfully.
No error can be found in log.
But, my instance can't get IP from dhcp agent.
Anyone know why this happen ??????
Thanks.
