Open Stack

Good explanation, thanks Vish.

http://docs.openstack.org/diablo/openstack-compute/admin/content/configuring-flat-dhcp-networking.html
has the --flat_interace requirement, and
http://docs.openstack.org/diablo/openstack-compute/admin/content/configuring-vlan-networking.html
describes the --vlan_interface requirement.

Thanks for asking Alexey. We can edit the page with the nova-manage
network create command also.
