# Enable nested VT-X/AMD-V

I recently ran across this while attempting to install Android Studio inside a Linux guest VM. The option to enable nested VT-X/AMD-V in virtualbox settings (for the specific VM) was greyed out.

Shut the guest down, launch cmd.exe inside the VirtualBox installation folder

> `VBoxManage modifyvm guest-vn-name --nested-hw-virt on`

The option tick box should be available and automatically selected.
