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.

A method of processing an input and output of a virtual machine, the method comprising:
- 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 backend virtual driver and the physical driver.
