[Users] Can oVirt be installed in a virtual machine?

Hi all, I am starting a small hosting business and want to use oVirt w/ KVM as my virtualization platform. I currently have 2 host servers and an iSCSI NAS. Do I need a dedicated machine to run oVirt? Can I run it from a VM? Can I use the all-in-one solution in a Production environment, with a 2nd host? ... would I need to install oVirt on both hosts, in the event that one of my servers went down? I am trying to see how I can survive if my oVirt server fails. It would be great if it ran from a VM but I can also see issues with doing that... Another option would be to run oVirt on my workstation and have it connect to my 2 host servers in colocation over the internet? Please let me know how you've accomplished an oVirt setup with 2 servers. Thank you! Nic
