# Interesting applications
## 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
network filesystems.
