I have two servers ServerA - Controller + network ServerB- Compute with eth0 and eth1 eth0 is reachable to the public network. eth1 is connected using cross cable to the servers

I am trying to configure neutron.

I am trying to launch the image using nova boot

nova --os-tenant-name TenantA --os-username UserA --os-password gre --os-auth-url=http://192.168.195.244:5000/v2.0 boot --image Ubuntu12.04 --flavor 1 --nic net-id=d40610af-c919-4b58-8db2-5ed6759c315e TenantA_VM1

It throws an error. Can you guide how to troubleshoot it
