Documentation virtio-9pfs for windows guests
## Host environment - Operating system: NixOS - OS/kernel version: Linux PC-001 6.19.11 #1-NixOS SMP PREEMPT_DYNAMIC Thu Apr 2 11:25:57 UTC 2026 x86_64 GNU/Linux - Architecture: x86_64 - QEMU flavor: qemu-system-x86_64 - QEMU version: 10.1.5 - QEMU command line: does not apply ## Emulated/Virtualized environment - Operating system: Windows 11 - OS/kernel version: <!-- For POSIX guests, use `uname -a`. --> - Architecture: x86_64 ## Description of problem I just noticed that the Wikipedia page for 9P mentions that windows these days has a 9p client built in as they use it to connect to the 9p server within WSL. > since Windows 10 version 1903, the subsystem implements 9P as a server and the host Windows operating system acts as a client. - [Source](https://en.wikipedia.org/wiki/9P_(protocol)) Because I was not able to find any documentation or other issue/feature-request about this, I decided to just open a ticket and inquire about it. So has anyone already looked into how to get a windows guest to work with 9p fileshares with QEMU? ## Additional information <!-- The line below ensures that proper tags are added to the issue.
