Install an appliance from the GNS3 Marketplace
This document explains how to download and install an appliance from the GNS3 Marketplace.
QuestionWhy would you want to use an appliance from the GNS3 Marketplace rather than manually configuring settings yourself?
Answer The GNS3 appliances are using GNS3 recommended settings and have been thoroughly tested. You will most likely have a much better user experience using the appliances. You will also encounter fewer errors if you use an appliance rather than trying to configure settings yourself and using untested images.
IMPORTANTIf you want to use IOSvL2, IOU, IOSv, IOS-XRv or ASAv images with GNS3, the GNS3 VM is mandatory when using Windows or Mac OS. This is because Qemu is better supported on Linux and faster when run with VMware (you can also use KVM). .
IMPORTANTSome vendors provide images of their systems for free. Others like Cisco do not. You will be need to provide your own Cisco images to use Cisco devices with GNS3. GNS3 are unable to provide Cisco IOS images. Please do not ask us or others to give you an image. You will need to either have an authorized account with Cisco or purchase a VIRL license to access Cisco images like the Cisco ASAv or IOSv. For VIRL, go here: http://virl.cisco.com/
