What kind of setup are you creating? Bridge_mapped networks? Private networks (with GRE tunnels)?<br>
<br>
If you are setting this up with GRE I'm missing the GRE tunnels in the "ovs-vsctl show" overview.<br>
You should have GRE tunnels to all Compute nodes in the network.<br>
<br>
To start troubleshooting I would first check if networking works between compute nodes:<br>
Start two VM's, on different Compute nodes, in the same subnet and see if they can reach each other.<br>
(If they do not get a DHCP IP just put in a static IP for now)<br>
<br>
There is bug with rebooting the machines running dhcp / l3-agent which might be good to be aware of:<br>
