When you run a Cisco Router/Switch on GNS3, your computer’s performance severely degrade. Therefore, you may experience performance issues when you design more advanced network topologies.

The main purpose of using the GNS3 VM is to minimize performance issues. If you want to add Router IOS image to GNS3 program, this Router IOS image will be uploaded to Server and run from it. As a result, you will be able to create more specific network designs and achieve greater performance improvements.

For installation, you must have one of the VMware WorkstationOracle VM VirtualBox, or VMware Fusion virtualization programs installed on your computer. You can easily import the GNS3 VM.ova file from the GNS3 website and import it with a virtualization program.
