Our install process has to encompass both hypervisors and virtual machines. The built-in image service (Glance) that is used with OpenStack is featureful but doesn’t address some of our image build requirements (such as dynamically and automatically deploying high availability virtual machines with DRBD.) With the exception of a single VLAN change (from an Embryo-style VLAN to Production), we are approaching zero-touch for our shard initial deployments, including auto-assembly of DRBD metadevices, deployment of custom base Xen hypervisors and virtual machine instantiation.

If I’m reading the steps correctly each machine is built from the ground up instead of using a universal base image.

Thanks!
