Open Stack

Please allow me to give some background regarding my question about nova-networking vs. Quantum.  I am setting up a OpenStack environment consisting of two nodes (controller and compute node).  My initial goal is to explore the inner workings of Cinder, and secondary goal is to understand the networking aspect (nova-network / Quantum).  I have a simple setup, so nova-network will suffice.  But if I want to down the line install and switch to using Quantum on this same setup, is that feasible and not too "complicated"?  Or should I just go ahead and install Quantum now and be done with it?  Any thoughts would be highly appreciated.

Also, if I run into networking issues down the line, will I have a "better" chance of getting issues resolved if I were using the later Quantum service.

Regards,
Ahmed.

There has been no final decision on whether some or all parts of nova-network will be removed.  It will not happen in Grizzly.  While Quantum can do many things that nova-network cannot, there are still some use cases that nova-network can do but Quantum cannot.  In Grizzly we're working to handle these.  Assuming that is achieved, we might consider removing/deprecating some aspects of nova-network in favor of Quantum.  At this point, nova-network is frozen in terms of new features, so the cost of maintaining it is relatively low.

Do you know if nova-network will go away (eprecated) sometime in the near future?

Quantum is optional component of the OpenStack. You you can use it or nova-network instead. Folsom release doesn't require Quantum. You should use it if nova-network features are not enough for you or you want to use some Quantum plugin for Open vSwitch or plugin supported hardware

I am familiar with that document and reading through it.  My question is do I need to install/use it to get a OpenStack up and running or is it optional?

Hello Ahmed,

Quantum installation and configuration docs for Ubuntu abd Fedora are available here:
http://docs.openstack.org/trunk/openstack-network/admin/content/ch_install.html

Hello,

I am following the steps in the document "OpenStack Install and Deploy –Ubuntu" to setup an openstack environment.  I would like to use Quantum for networking.  Is there an updated document (even in beta state) or does the same document apply?  It's just that I am not seeing a section on Quantum install/configure in this document.

Thank you,
Ahmed.
