Detailed Description
Virtual CPU (Intel x86_64)
The Virtual CPU represents a "CPU" to the hypervisor that is specific to Intel x86_64.
This Intel specific vCPU class provides all of the functionality of the base vCPU, but also adds classes specific to Intel's VT-x including the vmxon_intel_x64, vmcs_intel_x64, exit_handler_intel_x64 and intrinsics_intel_x64 classes.
Note that these should not be created directly, but instead should be created by the vcpu_manager, which uses the vcpu_factory to actually create a vcpu.

Constructor
Creates a vCPU with the provided resources. This constructor provides a means to override and repalce the internal resources of the vCPU. Note that if one of the resources is set to NULL, a default will be constructed in its place, providing a means to select which internal components to override.
- Precondition
- expects: none
- Postcondition
- ensures: none
- Parameters
-
id the id of the vcpu debug_ring the debug ring the vcpu should use. If you provide nullptr, a default debug ring will be created. vmxon the vmxon the vcpu should use. If you provide nullptr, a default vmxon will be created. vmcs the vmcs the vcpu should use. If you provide nullptr, a default vmcs will be created. exit_handler the exit handler the vcpu should use. If you provide nullptr, a default exit handler will be created. vmm_state the vmm state the vcpu should use. If you provide nullptr, a default vmm state will be created. guest_state the guest state the vcpu should use. If you provide nullptr, a default guest state will be created.
