Machine Specification for Testing Openstack

My company currently uses a hosted Openstack system. I would like to set up a single machine on which I can create a complete Openstack installation on few virtual machines, enough to cover all the node roles. The purpose of the installation will be as a learning tool and somewhere to test various configuration options and build up and tear down scenarios. The installation will include a couple of compute nodes, with a few guest instance running Windows :o( These guest instances don't actually have to do anything, other than boot up.

Just wondering what sort of specification a machine would need to run this? Hoping to do it with a desktop/tower machine.

You can test OpenStack on very simple hardware, including a laptop.

If you have a Windows 8/8.1 laptop or a Hyper-V Server I'd recommend:

In terms of resources, consider at least 6-8GB RAM for OpenStack and related services. This depends in particular if you want to test a minimal OpenStack deployments or also services like Ceilometer.

For the Windows images, consider at least 1.5-2GB RAM each and around 20GB of disk space. You can find the Windows Server 2012 R2 trial images here.

Consider a minimum of around 50GB of disk space for the entire OpenStack deployment, more if you need to test multiple images.

Thanks Alex, that's just the sort of info I was looking for. What about processing power? If I spit the node roles over say three VMs, add a couple of compute nodes with a Windows guest instance on each, will an i7 processor (or two) handle that, or do I need to go to a Xeon?

All depends to the response time you expect: for example here we run Tempest tests during development on i5 NUCs (dual core) or i7 laptops (quad core). CPU is rarely a bottleneck in test scenarios, you will most probably hit IO limits way before, even on a SSD.

Simon - You can very easily setup OpenStack from the master branch on your laptop, dedicated box or in a VMware guest machine within vCenter by using the os-ansible-deployment. Below is a link to instructions on how to setup. It's very easy.
