GNS3 on Apple Silicon

Before we work our way through the steps, I will start by pointing out GNS3 server has the following constraints when running on Apple Silicon: Lack of Linux KVM for x86_64 virtualized guests Slight performance penalty with emulated x86_64 Linux binaries (Rosetta ) The following are my results after testing a number of different Cisco device types: Device Working? Information IOL ✅ - IOL L2 ✅ - IOSv ✅ - IOSv L2 ✅ - ASAv ❌ Requires SSSE3 CPU instructions for cryptographic operations Catalyst 8000V ❌ Requires vmx or svm CPU flag for Linux KVM Nexus 9000v ❌ Requires vmx or svm CPU flag for Linux KVM As you can see, we’re primarily limited to Cisco (IOL , IOSv , Dynamips ) images, VPCS, and Docker containers....

GNS3 with Microsoft Azure

Microsoft Azure is one of the big three public cloud computing providers for services such as virtual machines (VMs), containers, server-less computing, and machine learning. Azure is a large platform, but we’re focused solely on the Infrastructure as a Service (IaaS) resources in this guide. The GNS3 architecture is comprised of three primary components: User Interface (UI), Controller, and the (Compute) Server. The Server is the component that puts a strain on computer hardware resources....
