FWIW, there's already two general purpose host<->guest communication channels for QEMU - virtio-serial (like a traditional serial port but giving them names & allowing many to be create) and virtio-vsock (like UNIX domain sockets, but across host/guest - alternatively like TCP/IP sockets, but without network devices involved) > I am now using a serial port to redirect to a pipe.

IIUC, you don't need to pre-create the pipe on Windows with QEMU chardevs. It looks like the code takes the filename you set, appends ".pipe" and then calls CreateNamedPipe to create it pipe.
