Virtual Network Lab Config Generator
Install
mysql -u {username} -h {hostname} -p virtnetlab < virtlab.sql
Edit the following variables in index.php:
define('DB_SERVER', 'localhost');
define('DB_USER', 'dbuser');
define('DB_PASS', 'dbpassword');
define('DB_DATABASE', 'virtnetlab');
From there, you are good to go. You can create devices and create cross connects between the devices, which will generate a KVM config that looks like:

Nifty, right!? It's very rough, with almost no validation and error checking, but can be very useful for generating complex topologies for IOS-XE CSR1000v and IOS-XR XRVR virtual images.
