From: Christian Schoenebeck <qemu_...@crudebyte.com>
The docs are ambiguous about the difference (or actually their
equality) between options '-virtfs' vs. '-fsdev'. So clarify that
'-virtfs' is actually just a convenience shortcut for its
generalized form '-fsdev' in conjunction with '-device virtio-9p-pci'.
And as we're at it, also be a bit more descriptive what 9pfs is
actually used for.

- pass-through options are:
+ Define a new virtual filesystem device and expose it to the guest using
+ a virtio-9p-device (a.k.a. 9pfs), which essentially means that a certain
+ directory on host is made directly accessible by guest as a pass-through
+ file system by using the 9P network protocol for communication between
+ host and guests, if desired even accessible, shared by several guests
+ simultaniously.

``local``
Accesses to the filesystem are done by QEMU.
