    Posted Feb 22, 2024 05:06 PM


    I posted about this problem I am having with getting GNS3 to work for the Switch Simulator. I did get it to work but I am trying to get it fired up again and things are not working. I am trying to get my GNS3 VM to run using Workstation Pro. I am getting this error:

    I can turn this off in the VM in order for the VM to start up. My GNS3 will not work because the KVM Support = False and needs to be True: 

    My steps:

    Enabled virtualization in the BIOS, everything is on. and running.
    I have disabled Hyper-V and the platforms.

    I am at a loss on what to do. Any assistance would be helpful.

    Perhaps something here may help:


    Keep in mind you need to allocate quite some CPU and memory to this VM to be able to do some simulation.
