Grizzly + Multinode with Quantum: VMs not getting IP

Asked by novelkumar

Hi,

I have the following setup of Grizzly:

Controller : eth0, eth1
Network: eth0,eth1,eth2
Compute: eth0,eth1,eth2

I am following https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst and installed the setup without any errors or issues.

When i create a VM using command ' nova boot --image Ubuntu --flavor m1.small testnova ', its does not get an IP assigned.

Contoller node:
