Recently virtio-9p support was added to bhyve.
On the host side it looks this way:
bhyve .... -s 25:0,virtio-9p,sharename=/path/to/shared/dir
It could also have ",ro" suffix to make share read-only.
In the Linux guest, this share is mounted with:
mount -t 9p sharename /mnt/sharename
In the guest user will see the same permissions and ownership
information for this directory as on the host. No uid/gid remapping is
supported, so those could resolve to wrong user or group names.
The same applies to the other side: chowning/chmodding in the guest will
set specified ownership and permissions on the host.
In libvirt domain XML it's modeled using the 'filesystem' element:
<filesystem type='mount'>
<source dir='/path/to/shared/dir'/>
<target dir='sharename'/>
</filesystem>
Optional 'readonly' sub-element enables read-only mode.
