Abstract:
A data processing system with technology to secure a VMCS comprises random access memory (RAM) and a processor in communication with the RAM. The processor comprises virtualization technology that enables the processor to (a) execute host software in root mode and (b) execute guest software from the RAM in non-root mode in a virtual machine (VM) that is based at least in part on a virtual machine control data structure (VMCDS) for the VM. The processor also comprises a root security profile to specify access restrictions to be imposed when the host software attempts to read the VMCDS in root mode. Other embodiments are described and claimed.

Claim (Index 17):
A method for securing a virtual machine control data structure in a data processing system, the method comprising:\n establishing a key domain (KD) in random access memory (RAM) of a data processing; loading a virtual machine control data structure (VMCDS) for a virtual machine (VM) into the KD; executing guest software in the VM in the KD in non-root mode; receiving a request from a virtual machine monitor (VMM) executing in root mode in the data processing system, wherein the request involves accessing the VMCDS; in response to receiving the request from the VMM in root mode, automatically using a root security profile to determine whether or not to allow the VMM to access the VMCDS.
