HARDWARE VIRTUALIZATION IN NESTED VIRTUALIZATION

摘要: it is a software implementation that runs on computers to run different programs like real physical machine. There are two classifications of Virtual Machines categorized by their use i.e. System Machine and Process Machine. Monitor or Hypervisor the layer provides virtualization. The operating system running virtual machine called guest system. From Operating designs development, Virtualization has great impact importance. Different techniques used in virtualization; each its own implementations under certain circumstances. One technique not truly efficient for other environment. Shared kernel, full kernel hypervisor virtualization be combined as well independently. Nowadays with binary translation most effective reliable technology ever ease use. VMware uses both hardware assisted We have discussed many types interrupt handling. How works over host explained this review. In nested there lack architecture support multi-level For reason up 10% overload. It possible overcome overhead 6-10% find better solution.
