You might want to consider ganeti. It works great from the command-line. There is a GUI for it as a separate project, but I've never used it. I've been running ganeti in dev/stg for 6-7 years and production for around 4, and it's been extremely solid. As far as running bash commands at first boot, in ganeti I have customized their "create" script to include a bash script that installs some packages, clones our Ansible setup, and then runs Ansible to set the machine up. We respin our entire staging cluster every other day (even machines one day, odd the next). http://www.ganeti.org/ http://www.ganeti.org/
