4th Gen Intel® Core™ vPro™ Processors with Intel® VMCS Shadowing
The white paper looks at Intel® Virtual Machine Control Structure Shadowing (Intel® VMCS Shadowing), a new capability available with 4th generation Intel® Core™ vPro™ processors that helps boost performance for nested virtual machine monitors (VMM).
While a nested VMM runs above a root VMM, such as Citrix XenClient*, it... still requires access to Intel® Virtualization Technology for IA-32, Intel® 64 and Intel® Architecture, and shares access with the root VMM.
While software-based nesting can enable sharing of virtualization architecture, sharing via software can affect application performance. Intel® VMCS Shadowing uses hardware assistance for software-based nesting, resulting in improved application performance.
