Abstract
A processing system includes a processor that implements registers to define a state of a virtual machine (VM) running on the processor. The processor detects exit conditions of the VM. The processing system also includes a memory element to store contents of the registers in a first data structure that is isolated from a hypervisor of the VM in response to the processor detecting an exit condition. The VM is to selectively expose contents of a subset of the registers to the hypervisor.
