This adds a new flag: share_dhcp_address which if enabled in multihost mode will allow all compute nodes to share an ip on guest network. The code will isolate the address using iptables and ebtables so it is only visible to the vms. This patch has two benefits: a) we don't have to use an ip address from every network for each compute node. This is especially valuable in vlan mode where the networks are generally small b) we can improve security by blocking all access to the ip on the guest network from outside the compute node. While we could do similar blocking using a different ip for each node, it makes dhcp setup much more complicated if a vm is migrated to another node.

OpenStack Nova README
OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of virtualization technologies, including KVM, Xen, LXC, VMWare, and more. In addition to its native API, it includes compatibility with the commonly encountered Amazon EC2 and S3 APIs.
OpenStack Nova is distributed under the terms of the Apache License, Version 2.0. The full terms and conditions of this license are detailed in the LICENSE file.
Nova primarily consists of a set of Python daemons, though it requires and integrates with a number of native system components for databases, messaging and virtualization capabilities.

To learn how to deploy OpenStack Nova, consult the documentation available online at:
In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
Developers wishing to work on the OpenStack Nova project should always base their work on the latest Nova code, available from the master GIT repository at:
Developers should also join the discussion on the mailing list, at:
Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests. Further developer focused documentation is available at:
Changes to OpenStack Nova should be submitted for review via the Gerrit tool, following the workflow documented at:
