Hi Rodrique and Daniel,

It's actually just recorded presentations, and they are available for 90 days I believe.  So you may still be able to register for the event and listen to the presentations for a while.

Right, so today Foreman just takes images that already exist and what you're looking for is a feature enhancement to Foreman that would integrate with something like Image Factory or Oz to build new VM images from source media and then push those images into Glance.  Do I have that right?

You are exactly right. I would be happy with just using OZ alone to build images and using some other tool to push those images into Glance. I believe fog can do this, I know Foreman uses fog to talk to Openstack, ovirt etc.. If anyone got a work script that uses OZ to build, then push images into Glance, please share.

Apologies for not being in the lounge today to take the questions live.
 I had another commitment and couldn't attend.

It's a service similar to Cloud Formations in Amazon AWS.  It provides the ability to define a template that describes multiple VMs working in concert.  So you would define a template with 1 or more VM definitions, and then tell Heat to launch that template.  Heat then uses the OpenStack Nova APIs to launch the VMs in the proper order, waiting for things like dependencies in one VM before launching the 2nd.

I've included some of the Heat folks on this thread.  I'm sure they can do better justice to your question than I could :)

Foreman could definitely be used for both bare metal server provisioning for OpenStack core services and Compute Nodes while also being used to provision the VMs that will be in the cloud.  I thought that Ohad (Foreman creator/maintainer) had done some integration work (or maybe it was just planned) to better integrate Foreman w/ OpenStack from a guest provisioning perspective (using Fog as an abstraction layer I think)

Ohad, any additional thoughts here?
