I've just checked out and built projects/hyperv and everything looks good.

>> Hi Pavel,
>>
>> Thanks for inquiring about the BSD drivers for Hyper-V. We (Microsoft) are actively working on these drivers and the intent is to get them integrated in to the kernel within the next month or so. There are some issues we are trying to address:
>>
>> a) Witness panic during boot time due to a specific memory allocation.
>> b) Bypass usage of disk labels to ensure that devices do not get reordered under FreeBSD.
>> c) Locks up on 32 bit builds.
>> d) Lack of KVP support for BSD drivers
>>
>> We are working hard every day to finish these items.
>>
>> Even though an official announcement has not gone out, I would highly encourage you to start testing the drivers. As they are in project branch now they should be easy to compile. The only requirement is to set up disk labels before rebooting a kernel that includes the Hyper-V drivers otherwise the system will not boot up.
>>
>> Please let me know if you have more questions or have feedback.
>>
>> Thanks again for your interest.
>> Abhishek
