Abstract
Memory security technologies are described. An example processing device includes a processor core and a memory controller coupled to the processor core and a memory. The processor core can determine that an exit condition to transfer control of a resource for a processor core from a first virtual machine monitor (VMM) to a second VMM has occurred. The processor core can also determine whether a control virtual machine control structure (VMCS) link pointer is valid. The processor core can also determine whether a reason value corresponding to the control VMCS link pointer is set. The processor core can also determine whether the reason value is set to zero. The processor core can also determining whether an exception bit corresponding to a specific exception type of a reason value is set. The processor core can also transfer a control of the resource from the first VMM to the second VMM.
