That's a step in the right direction, but don't make us use Hyper-V when most of us are already using VirtualBox. That's one more thing to add to my stack that is different than my tooling that works with all other operating systems I test on. Most developers using vagrant use VirtualBox. Now I have no problem if you make things work with Hyper-V, but please make things work with VirtualBox as well. Does hyper-v even run on Linux or OS X?

PSS if you are an MS engineer working on this stuff, can you please contact me via the email in my profile. I didn't see an email in yours.
