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....
