OpenStack Compute (nova)

I can not connect to running instance whit FlatDHCP configuration

Asked by Daniel Nunez E.

i try to deploy multinode architecture whit Diablo openstack
I have a cloud controler in a vm in virtualbox colled S1, it has nova-network, nova-scheduler, nova-network. Whit 2 interfaces.
The server2 is a physical PC, it has a nova-compute and virtualize whit kvm.
