This question has been answered before, in the last 2-3 months, if you
search the archive.
The short answer is that Windows Desktop OS only supports a single CPU
socket, optionally with many cores. The default in bhyve is to expose
each virtual CPU as a separate socket. There are a set of sysctls that
let you control this, so you can instead expose the 4 cpus as cores of a
single socket, and it will then work with Windows 8.1/10, but I don't
recall what they are off the top of my head, but they are in the archive
which you can browse here:
