As far as I know, EVE-NG and GNS3 only work on Intel Macs. The VMs require Intel hardware, and their developers have not released a version that runs on ARM architecture CPUs like Apple Silicon.
if I remember prior research on this, they both also require nested virtualization, which is not supported by Apple on macOS’s hypervisor on Apple Silicon and is not available for Fusion.
You will have to take it up with their developers as to when and if they are going to provide a version that works on Apple Silicon Macs.
