That is currently only a part of the x86_64 build-tools, so I had to learn a way to run x86_64 executables on ppc64 cpu. The first option is full emulation (emulating x86_64 kernel and apps), the other is QEMU’s user mode translation (emulating only user-mode, translating syscalls to a running ppc64 kernel). Let’s have a quick look at the QEMU user-mode translation.
It is actually quite easy to boot Windows virtualized using KVM. But to properly use the UEFI bootloader, suitable QEMU arguments are required. Here is a lightly commented QEMU command I use to boot virtual Windows 10 I have on a separate partition.
