Great, now my GNS3 VM is supporting KVM I can proceed with importing appliance which need KVM support. Verify the same on GNS3 VM console again. Later I realized that, I missed to enable Virtualization for my GNS3 VM (on ESXi console) and proceeded with same. So, I went to GNS3 VM console, yes NO KVM Support ! Still I proceeded with main server I got error on GNS3 saying, “no KVM support”. See, both remote server or GNS3 VM no supporting KVM. I have verified that Virtualization has been enabled for my ESXi physical host and tried to import an appliance. In my case, I am using GNS3 UI on a VM (Ubuntu with Graphics) and GNS3 VM on another VM both are running on top of ESXi (ver 6.7.0). Because, most of the appliance need KVM support on GNS3 VM otherwise you won’t be able to import network appliance to GNS3. While setting up separate GNS3 VM, you need to enable KVM support for the GNS3 VM (even if you are using all in one). And the simple configuration to resolve the same. I just want to share the common mistake, which newbies do when setup GNS3. This post is not meant for explaining GNS3 read GNS3 Documentation for more details. Once in a blue moon it will work and actually import the template, otherwise it's a complete headache - which is why I'm trying to import a standalone VM running in VMware into my GNS3 environment instead of using the default ubuntu template that they recommend.GNS3 (Graphical Network Simulator) is the most popular – open source, free software – tool for designing and simulating network infrastructure. The only way around this is to close the import staus box, quickly hit ctrl+q to quit GNS3, and then hit X on that pop up one more time when it inevitably shows up again. If I close that again, it will keep popping up saying it's still trying to import the image but is stuck at X%. When I hit X to close the import, it will pop up again a moment later. It dies and I've waited 30 mins + and it never moves. I think "ok, I'll just give it some time, maybe it's still working." Nope. it will get to some random point and freeze. I want to start a vm, capture all the networking traffic related to that, and then open the browser without generating any traffic and only generate traffic when I enter in a website to go to.ĮDIT: I forgot to clarify, I have tried multiple times to import devices using existing GNS3 templates, downloading the software required and then importing it into GNS3 on the GNS3 server, and every. I'm using a full fledged stand alone Ubuntu VM because I've tried using the docker container GNS3 firefox VM and it opens extra tabs in privacy mode when I launch firefox and I really do not want that for what I'm trying to accomplish.
