# version v0.9 (2015-05-07) has the following checksum: sha1sum create_virtual_machine_with_windows_7.sh.tgz 422d56bdf0e76a88071747afff184361e0b4528e
The virtual machine is configured with paravirtualized drivers for the virtio and spice protocol. A private network with iptables rules does not let Windows get out of the VM (no internet access by default). You can get internet access for the virtual machine if you reconfigure iptables.
