# This is a script which uses QEMU to start a VM or set up the VM with a pre-defined installer
# when the virtual hard-drive cannot be found. It was made to quickly recreate a new VM in case
# the old one was deleted (maybe because someone messed arround with it)
# All the arguments QEMU needs to start the VM with the right parameters
# are also stored in this script and can be modified.
# The default OS installer is currently a Link to the OpenSUSE net installer

# This scripts fetches the latest Linux Mint ISO file with Cinnamon desktop for 64bit systems
# and stores the iso file in a temporary file. The script also checks the sha256 checksum of the
# downloaded file and returns the path to the file if the checksum is correct. Otherwise the
# script returns an error code.

# To get the newest version of Linux Mint, the script fetches the content of the download page of a local mirrot
# and extracts the version numbers from the links to get the highest version number.
