Abstract: Provided is a method of processing an input and output of a virtual machine. The method includes transferring, by a frontend virtual driver of a first virtual machine, an input and output command to a hypervisor, storing, by hypervisor, a context of the first virtual machine in response to the input and output command, executing, by the hypervisor, an interface of each of a physical driver and a backend virtual driver, installed in a second virtual machine independent from the first virtual machine, in the first virtual machine, and transferring, by the first virtual machine, the input and output command to an input/output device through the interface of each of the physical driver and the backend virtual driver.

Abstract: Provided herein is a server virtualization method of a multi-node system, the server virtualization method comprising setting one of a plurality of computing nodes as a hypervisor master and at least one of remaining computing nodes as at least one hypervisor slave, allocating a virtual resource corresponding to each of the at least one hypervisor slave in the hypervisor master, and instructing, when a workload is input, a hypervisor slave determined based on a use state of the virtual resource corresponding to the each of the at least one hypervisor slave to process the workload.

Abstract: An apparatus for providing security services based on virtualization, the apparatus including: a host virtual machine in which a host operating system that controls a general execution environment is operated; a secure virtual machine, which is separated from the host virtual machine, and in which a secure operating system operates independently of the host operating system; and a virtual machine monitor portion configured to allocate the host virtual machine and the secure virtual machine by virtualization, in which the host virtual machine and the secure virtual machine may access system resources only through the virtual machine monitor portion, and the virtual machine monitor portion classifies user input signals received from a user, and transmits the received user input signals to the host virtual machine and the secure virtual machine.
