We're able to save time and money by having'standard' VMs for windows dev, rails dev,build machine, windows QA, etc. [...] It wasreally great when the customer handed overtwo VMs at the beginning of the project, andwe were able to just load up those VMs andstart our development.

You quickly forget about the virtualization except

when you need it. When you need to migrate tonew hardware or increase RAM on a moment's

notice. Ill never [again] install a Linux instance that

doesn't start with Xen.
