No, Mu has nothing to do with this, Mu is a fork of EDK2 with a nice GUI and continuous update whatever stuff. This is firmware. Hyper-V uses firmware to boot an OS, but that's all inside the VM. More to the point though, MS recently made a public Hyper-V API thingy. Windows Hypervisor Platform I think it's called. It's similar to how KVM, bhyve (vmm.ko) and Apple's Hypervisor.framework (its kernel counterpart actually) work. Now you can use Hyper-V itself + any third party frontends that use that API. E.g. the Android emulator is going to switch to this. VirtualBox/VMWare should leverage these APIs but they don't because they're way too invested in their custom kernel modules already.
