FWIW, boot2docker became my favorite all-purpose, ready-to-run, ridiculously-small-and-therefore-insanely-fast-to-download VM image.
It's faster to download it (it's 25 MB) and start it with qemu, than to go through the clicky-pointy interfaces of VirtualBox etc., or go through the download of a full Vagrant box. This is game changing.
