VirtualBox now supports nested virtualization on Intel processors. In the past, this was only available on AMD processors. This opens up a whole range of applications with VirtualBox: You can run your GNS3 topologies on VirtualBox, you can nest hypervisors and have some fun. Great to see VirtualBox support for nested virtualization now available on both Intel and AMD processors.

These are the commands I used to enable nested Virtualization via the CLI:

Open a CMD prompt:

==================

Use these commands:

cd C:\Program Files\Oracle\VirtualBox

VBoxManage.exe list vms

VBoxManage.exe modifyvm "GNS3 VM" --nested-hw-virt on
