-## Virtual machine hard disk over a network protocol
-
-If you happen to use a form of network filesystem, such as 
-[GlusterFS](http://docs.gluster.org/en/latest/),
-you can keep the machine hard disk off the host and put it on another computer.
-There might be a some form of lag depending on the hardware, protocol and 
-network connections.
-
-An example with GlusterFS might be:
-
-    VHD_NAME="gluster+tcp://server-address/gluster-volume/"${IMG_NAME}"."${VHD_TYPE}""

-This will work provided that you install the QEMU GlusterFS block module 
-package (if it's not already present in the QEMU package itself).

-You should consult the QEMU's manual to learn about all possible compatible
