You're cross-posting this to the libvirt users and virt-tools
developers list, and yet you seem to be running bhyve directly so
neither libvirt nor virt-manager are involved.

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

Anyway, since I'm already replying...

... 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 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 ;)
