Customising MAAS to use multiple NICs on deployment

Following on from my first post on Customising Ubuntu MAAS to deploy Puppet we can further customise MAAS to deploy with multiple network interfaces on deployment.

If you are deploying Openstack then recommended architecture includes multiple network interfaces for each server node.  For a production deployment there are often as many as 4 NICs per node.

Openstack Operators are getting together to create the Openstack European Operators Meetup, to share experiences with running Openstack in production environments.

Welcome to Stack Evolution Launch

Today we are launching our new website on

I am proud to announce our new website to showcase our services and expertise around Openstack.

I have been working on Openstack since 2011 and it has developed from a basic project barely able to be installed, up to a solution backed by over 200 companies and used in production by big name brands, service providers and enterprises looking to reduce their cost of IT infrastructure.


Welcome to Stack Evolution.

Please use our site to browse our content.
Please contact us for services around Openstack mainly in the UK and Northern Europe.
We specialise in consultancy, training and we do not affiliate specifically with any vendor, but we have good contacts at all the open source vendors, including Canonical, RedHat and Mirantis.

We offer training courses, custom in-house training for Openstack either with a vendor solution or only use purely open source components.
