1.2. Support for Nested Virtualization

This release adds support for nested virtualization. This feature is only available on host systems that use an AMD CPU.

Nested virtualization enables you to install a hypervisor, such as Oracle VM VirtualBox, Oracle VM Server or KVM, on an Oracle VM VirtualBox guest. You can then create and run virtual machines (VMs) in the guest VM.

Configure nested virtualization by using the VirtualBox Manager or the --nested-hw-virt option of the VBoxManage modifyvm command. See Nested Virtualization.
