I assume that a support list for bhyve users exists. That would be the appropriate forum to ask for help.

I will point out that virtio-9p and virtiofs are two completely different things. You've configured the former in the host, and are trying to access data using the latter in the guest. That's not going to work. I could not find confirmation that either bhyve supports virtiofs or that 9p can be used from Windows from a quick search. I'm afraid you might be wading into entirely uncharted territory. > I've attached some screenshots to help you to understand what's happening. > > https://ibb.co/m5vm1hd > https://ibb.co/Qd6TS5d > https://ibb.co/3018SGd I highly recommend changing your OS' language to English before grabbing screenshots. Limiting the pool of people who might be able to help you to those who can understand Italian is unlikely to make things any easier for you ;) -- Andrea Bolognani / Red Hat / Virtualization

It seems more a problem of Device drivers and Windows 11. I think it might be worth a shot. Hopefully FreeBSD is planning to implement virtiofs support in bhyve at some point in the not too distant future, but in the meantime other users might be able to suggest alternative ways to implement host/guest file sharing.

ok I can't because bhyve does not support nested virtualization. sorry for the mistake.
