Chris Titus shares an excellent video tutorial on setting up a Windows VM on Linux using QEMU/KVM and Virtmanager. It is really brilliant.

Note the link is time-stamped on purpose because he shows a typical setup first and then deletes it and starts the right way. The link is directly to the right way.
After initial setup, the video continues and references this guide:
