I’ve written about deploying devstack before in Contributing OpenStack Support to jclouds. That post covered running devstack locally in VirtualBox. I’ve been using that method for a while now but with a devstack env in VirtualBox, a jclouds dev env, browser, chat client, mail client, etc. etc. etc. all running on the same laptop it gets bogged down. I’m pretty sure I heard gears grinding and smoke was pouring out of the laptop at one point. I just don’t have the cores, RAM, and RPMs to run everything smoothly and you need smoothly or development starts to suck.
