#  Each entry in the configuration file `/etc/qemu-web-desktop/machines.conf` 
#  spans on 3 lines:

#  -  [name.ext] 
#  -  url=[URL to ISO, QCOW2, VDI, VMDK, RAW, VHD/VHDX, QED virtual machine disk, optional]
#  -  description=[description to be shown in the service page] 
#
#  Images listed in the configuration file without a `url=` parameter are
#  expected to be downloaded by hand and installed into
#  `/var/lib/qemu-web-desktop/machines` by the local administrator. Then, just 
#  specify the [name.ext] and description.
