Kudos to Microsoft for listening to users and allowing the rest of the Linux distros to run optimized on Hyper-V. Note however that although Microsoft has open sourced and submitted the driver code to the Linux Driver Project, it is not yet part of the main Linux kernel. The code still needs to be reviewed and tested and submitted for official inclusion into the Linux kernel tree. Once through this process, these integration components should eventually gain acceptance and make their way into most Linux distributions.
