    Minikube docs are recommending AGAINST using 9P. I hope this changes things, not only in terms of speed but also making it more reliable.

    At the moment shared filesystems are a major PITA to setup/maintain over different platforms.

    LOL me too!

    Sorry, I mean I use it with Linux guests. I have not yet tested with Windows. Samba is what I use with Windows, which is OK. The issues with samba is that Linux does extra file caching, and with virtiofs you can disable this.

    I use virtiofs. It is much more performant than 9p. At least until now.

    Isn't WSL2 using 9p? Can't that be used?

    This improved performance makes it more desirable, so there will be more impetus.

    Windows host support for 9pfs export to guests V2 patch will be merged "soon".

    There's a 32-bit Windows guest 9pfs driver here.

    I've used sshfs for Windows guest to mount Linux host fs where high performance isn't important.

    On WinXP I even used Samba. <Shudder/>.
