# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
