How to create custom Guest VM for GNS3
I’ve spend countless hours on GNS3 market place to find a working Windows 7 Guest VM to run Cisco ASDM (as you might know it requires Java to run) but all Win 7 images failed to run. Then I tried Ubuntu Desktop image it also failed to run. Downloading and uploading these images to GNS3 consumes huge amount of time and it is really annoying to find out that they don’t work.
So i decided to make my own Guest VM. I choose Lubuntu because it is light weight and it’s a modern OS.
Things we’ll be doing;
- Creating a Lubuntu VM on VMware W.S.
- Installing it.
- Installing Open VM Tools.
- Installing SSH server.
- Downloading Java for Linux.
- Updating Lubuntu.
- Creating a clean snapshot of Lubuntu.
- Initial config. of ASA firewall.
- Creating a simple topology.
- Connecting ASDM from Lubuntu Linux.
