Now we will configure the Networking of the GNS3 VM. Now, when you boot, you should not see the error. This must be done when the VM is powered off. Place a check in the Expose hardware assisted virtualization to the guest OS. To enable nested virtualization capabilities on the GNS3 VM, open the WebUI in vCenter and in the Edit Settings dialog box under the CPU, you will see the option for Hardware virtualization. By default it is set to DHCP.Īlso, since the VM uses KVM, so you must enable nested virtualization or you will receive the error message below. In this particular lab environment, I didn’t have a DHCP server running, so the ethernet adapter wasn’t able to pull an IP address as you can see below. Upon the first boot, you may be prompted to configure the network settings. I love the extending tongue of the GNS3 logo to show boot progress. Either using the WebUI or vCenter client, deploy the template. Once you have downloaded the OVA template, you will deploy this in the normal means of deploying an OVA file in vCenter.

Notice the Download the GNS3 VM link at the bottom. You will need to create a free account if you have not done so already. Navigate to the GNS3 official website and download the OVA template for VMware ESXi. However, I found the documentation a bit all over the place when it came to setting up the GNS3 VM so I wanted to quickly encapsulate what I did to get it up and running in my ESXi lab environment. One of the bigger changes lately is the use of the GNS3 VM instead of the IOU VM that has replaced this functionality moving forward. I had recently refamiliarized myself with GNS3 and it has changed a good amount since the last time I had used it.

Anyways, without getting into a quick review of the differences between the different products, I wanted to write up a quick post on how to setup GNS3 VM VMware ESXi installation. VIRL is maturing and getting there as a product, but the VM Maestro interface leaves a lot to be desired. I definitely prefer the interface of GNS3 over other products such as VIRL. GNS3 has definitely matured as a product and offers tremendous functionality especially if you look at the cross vendor platform support that it offers.
