[Openstack-operators] I have finally created an instance, and it works! However, there is no ethernet card

By "defined a network space for your instances", does that mean going
through the process as described in
I got part way through that when I realized that the procedure was going to
bridge packets through neutron. That's not what I want. I want the
packets to go directly to the physical router. For example, I have two
tenants, with IP addresses 10.50.15.80/24 and 10.50.18.15.90/24.and the
router is at 10.50.15.1. There is a nice picture of what I am trying to do
. But if the hypervisor doesn't present a virtual device to the guests,
then nothing else is going to happen. The network troubleshooting guide
does not explain what to do if the virtual NIC is missing.
