This will open the low level edit of the /etc/network/interfaces file where you can edit your network settings. Select the Networking – Configure networking settings option in the menu. Now we will configure the Networking of the GNS3 VM. Now, when you boot, you should not see the error.

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.

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.
