Description

METHOOD OF CHANGING OPERATION ENVIRONMENT AND APPARATUS FOR THE SAME}

The present invention relates to virtual environment management, and more particularly, to a virtual environment management method for managing a virtual environment based on context information and a terminal device using the same.

As processor technology evolves, there is a steady increase in interest in virtualization technology. Virtualization technology refers to a technology that allows multiple operating systems to be operated independently from a single physical device.

In this virtualization technology, the physical device does not directly execute the application code of the application, but at least one virtual machine implemented in the physical device interprets the command code to execute the application.

According to this virtualization technology, a virtualization layer is formed on a host operating system of a physical device, and a plurality of logical virtual machines are created on the virtualization layer.

A guest OS may be installed in each of the plurality of virtual machines, and applications supported by the corresponding OS may be installed on each guest OS. Accordingly, the plurality of virtual machines can function as a self-contained platform running their own operating system or software application.

When the virtualization technology is used, a virtual machine manager is provided to manage a plurality of virtual machines. The virtual machine manager manages virtualized hardware resources and creates various virtual machines such as creating, deleting, starting, and restarting virtual machines. You can manage your machine.

Moreover, in this virtualization technology, not only virtual machines can use virtualized hardware resources but also provide isolation between each virtual machine. This is one of the most notable features among virtualization technologies. It virtualizes one hardware resource so that if one virtual machine fails among the virtual machines in use, it will not affect other virtual machines at all and provide higher reliability. Because it can.

In addition, even if one virtual machine is invaded or attacked from the outside, the virtual machines are completely separated from each other, and only the corresponding virtual machine is attacked and does not affect other virtual machines of the same hardware at all.

In particular, the virtualization and isolation of memory is achieved through support, and even if a system is completely destroyed or occupied by an error or external intrusion, the resource of the memory in question is already completely separated from the resources of other virtual machines. This is because the problem does not spread to other virtual machines.

On the other hand, smart phones, which combine the functions of mobile communication terminals and PDA functions, have been in the spotlight in recent years, and these smart phones have larger memory and higher performance CPUs than conventional mobile communication terminals, and execute various applications and voices. It includes an operating system to support data communication and PC linkage, such as Apple's iOS and Gugul's Android.

As a result, smartphones can perform tasks like traditional computers such as Internet browsing, email, gaming, and e-commerce. For example, a company can create and provide a business application to a user, and a user can download and install the application through a smartphone, and then execute the installed application to perform a task.

When virtualization technology is applied to a smartphone, at least one virtual machine may exist in the smartphone. Accordingly, at least one virtual machine may exist in the smartphone, and an application may be installed in the at least one virtual machine.

When at least one virtual machine may exist in the smartphone, the user may install different applications on the at least one virtual machine, respectively, and switch the virtual machine as needed to execute the application installed in the virtual machine.

For example, in order to use at least one virtual machine as a work virtual machine and a general purpose virtual machine, a user installs an application for a company job on a work virtual machine, a user favorite application on a general virtual machine, You can switch virtual machines as needed to run applications installed on them.

However, in order for a user to switch at least one virtual machine existing in the smartphone, there is a problem in that the state of a running virtual machine must be changed to a stopped state or an end state, and the state of the switching target virtual machine must be changed to a running state. .

Contains the hypervisor to change.

Here, the hypervisor may manage each state of the at least one virtual machine as one of an execution state, a stop state, and an end state.

Here, the hypervisor changes the state of at least some of the at least one of the at least one virtual machine to the stopped state or the terminated state, in order to change the driving environment provided by the at least one virtual machine, You can run a new virtual machine.

Here, the hypervisor according to a predefined virtual environment change rule stored in correspondence with the predefined context information causing the change to the virtual environment of the at least one virtual terminal and the virtual environment corresponding to the context information. The virtual environment corresponding to the information can be determined.

Here, the at least one virtual machine may be a machine that virtually expresses the same operating system or different operating systems.
