Abstract
A mechanism is provided for performing secure recursive virtualization of a computer system. A portion of memory is allocated by a virtual machine monitor (VMM) or an operating system (OS) to a new domain. An initial program for the new domain is loaded into the portion of memory. Secure recursive virtualization firmware (SVF) in the data processing system is called to request that the new domain be generated. A determination is made as to whether the call is from a privileged domain or a non-privileged domain. Responsive to the request being from a privileged domain, all access to the new domain is removed from any other domain in the data processing system. Responsive to receiving an indication that the new domain has been generated, an execution of the initial program is scheduled.
