Add a 3rd Network Adapter that will be in Bridged mode and connected to the Loopback adapter (Microsoft KM-TEST Loopback Adapter).Download the GNS3 VM version that matches the installed GNS3 version.Rename the new Loopback adapter to “Loopback”.Install a new Loopback interface (reboot required).There are setup instructions for it below. We don’t install SuperPutty from here because its not the latest version and the first thing it does when you open it is bug you about upgrading to the latest version. We don’t need Dynamips/QEMU/VPCS/Cpulimit because we’ll be running everything off of the GNS3 VM server.

This install is intended for running IOU/IOL images on the GNS3 VM because it is the preferable way of running IOS in GNS3 now.
