2. Install apache webserver: `sudo apt -y install apache2 && sudo rm -f /var/www/html/index.html && sudo systemctl enable apache2 && sudo systemctl restart apache2'
3. Modify the ip address in the virtualbox/scripts folder to the ip of your base machine:

find scripts/ -type f -name "*.sh" -exec sed -i 's/172.16.0.143/<your-ip>/g' {} \;

CentOS 7.2/Fedora 24

1. Run a cron job daily using the script, scripts/repoupdate

3. Modify the ip address in the libvirt/scripts folder to the ip of your base machine:

find scripts/ -type f -name "*.sh" -exec sed -i 's/172.16.0.143/<your-ip>/g' {} \;
