## 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.
