I'm currently testing the F22 Project Atomic as a guest on Windows 8.1 Client Hyper-V. I can convert the TC 2 beta qcow2 to vhdx via qemu-img, boot the disk with the credentials ISO in a Generation 1 Hyper-V guest, log in as "fedora", sudo to "root" and do a 'docker run' pulling an image from Docker Hub.

I still need to test browsing to a host-only network adapter from the Windows desktop but that's just a matter of reading a few more manuals. And generation 2 VMs don't work and would need to work for this to be supportable. So I would like to propose supporting this use case in Fedora 23.

I don't have an effort estimate at the moment. A minimum task list so far would be:

1. Operationalize the conversion from qcow2 to vhdx in the release process.
2. Get generation 2 machines working. This may have to wait until Windows 10 ships.
3. Define test scenarios and build Windows PowerShell scripts to execute them.
4. Documentation!

I'll volunteer for 3 and 4 for now - it's on my road map for my remix anyway.
