Para-Virtualization)
The two most common virtualization methods are full virtualization and quasi-virtualization. With full virtualization, there is a layer between the virtualized operating system and the hardware to determine access. This layer is called a system manager or Virtual Machine monitor (vmm ). Quasi-virtualization is similar to this, but system management programs operate in a more collaborative
