virtualization support to the processor. However, both IBM and Sun have adopted a hardware-based class virtualization strategy, in addition to the hardware to add support for virtualization, but also in the firmware layer to join the corresponding class virtualization VMM layer, the upper layer of the operating system needs to be modified according to the VMM layer interface. Provides comprehensive, collaborative support for virtualization from the processor to the firmware layer to the operati

KVM Virtual Machine IntroductionIntroduction to a KVM Virtual Machine (kernel-based Virtual Machine) is an open-source system virtualization module. It has been integrated into major Linux releases since Linux 2.6.20. It uses the Linux Scheduler for management, so compared with Xen, its core source code is few. KVM has become one of the mainstream VMM in the academic field. KVM virtualization requires hardware support (such as Intel VT or amd v ). Is

Where Vn is a non-exhaustive set of non-terminating symbols, Vt is a set of finalization symbols, p is a production set, and S ∈VN is the grammatical identifier (also known as the start symbol).
