Purpose: This set of scripts will dynamically create virtual machines along with networks and repos then setup connections dynamically between them. It works in either offline or online mode and is an all in one solution. 
copy all files to a CD or USB device then run the start.sh ( sudo bash ./start.sh ) from that device.

Ussage: To create virtual machines dynamically for testing purposes and have easy ability to reset those machines.


Run the start.sh script in the base folder, this will copy the contents to the /LabSetup folder on the local machine and create two desktop icons.
After this has completed, ensure you have your networking files, packages, and kickstart files placed in the proper locations as outlined below, then run the "VirtLab Environment Reset" icon on the desktop. This will start the processes of creating your virtual lab environment. After the virtual machines are created and waiting for you to login, run the desktop icon again to finish the setup. Be sure to read all warnings.

NOTE -The script will see how much memory is available on the local machine, then divide that memory by the number of VM's you are creating.


The hosts file is created based off the VM names, IP address, and the virtnet files data. The hosts information should be dynamically created and you can verify by running the command: cat /etc/hosts

The contents of the files are encapsulated between the -startcontent- and -endcontent- tags, everyting inside those tags are the text.


Packages--
Create a new folder and name it whatever you wish the repo name to be, then inside that newly created folder create a folder named Packages and place all the packages you need available to your lab environment in there. The setup script will automatically create the repos and add them to this machine along with the virtual machines.

Networking--
place the networking setup file in the virtnet folder. if you need more than one network created then just create a separate file with different settings. Remember not to duplicate IP ranges or interfaces. please see exmaple at end of readme.

Virtual Machines---
For each new VM create a folder under the /LabSetup/KS folder and name the folder the name you want the VM.
Place the kickstart file inside that folder name it ks.cfg. Edit the file to match the networking settings required and packages you wish to have installed by default. please see exmaple at end of readme.
