+	  Say 'y' here if you want QEMU to provide a plan9 virtual "share"
+	  accessible from the guest OS for relatively fast access to host
+	  files.
+	  
+	  This requires that the guest OS is capable of accessing plan9
+	  ressources (typically, in Linux, this is done by a network
+	  file-system called 9p, and can be accelerated by using the 9p
+	  virtio).
