Artom Lifshitz 57ab45323c Update libvirt enlightenments for Windows
libvirt has a set of enlightenments in domain XML that make it
friendlier for Windows guests. We already enabled a few of these, this
patch just completes the list. All of them are available in libvirt
4.7.0 (QEMU 3.0) [1], which is way below our current minimum libvirt
and QEMU versions, so we don't need any extra checks.
