I use vagrant + virtualbox myself and spin up development environments on the fly. It really is "the way to go". Work actually provides vmware fusion (and a license for vagrant), which also works pretty well. Fusion offers more networking options (like if you're working on pxe boot images), but I found that it's easier to track and support virtualbox images.
One thing that I've thought about trying though, is Boxen. Github supports hundreds of developer macs and they built this framework to do so. It looks pretty incredible. https://github.com/blog/1345-introducing-boxen
