as far as I know it still not possible to cross build a legal QEMU for
Windows on a Linux machine due to the license limitations of the SDK
which is needed. The header files needed for the QEMU build are "All
People often ask me to add WHPX support to the QEMU installer for
Windows, but I have to tell them that I cannot do that currently.
This problem could be solved if the necessary header files were added to
QEMU with a permissive license by someone who has the rights to do so.
