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: https://lists.freebsd.org/pipermail/freebsd-virtualization/ -- Allan Jude
