Hyper-V - Wikipedia
https://en.wikipedia.org/wiki/Hyper-VThe following table lists supported guest operating systems on Windows Server 2008 R2 SP1. Fedora 8 or 9 are unsupported; however, they have been reported to run. Third-party support for FreeBSD 8.2 and later guests is provided by a partnership between NetApp and Citrix. This includes both emulated and paravirtualized modes of operation, as well as several HyperV integration services.
