Hi All,
Hyper-V support for X86 or X86_64 were noticeably missing. There is a previous patch for Kernel 3.3 but never maintained or merged into trunk. Here's my take on adding the Hyper-V support for the current kernel. No new sub targets or profiles are created, as long as the target is x86 or x86_64. The generic works well or any other profiles.
Also added a new VHD target image menu . The latest stable qemu-img supports Hyper-V vhd and vhdx. The old & current qemu 0.14.1 builds invalid vhd images. I am working on updating it to 2.0.0. Currently I am converting vmdk into vhd using third party tools.
