At this time, the management server 30 may initialize the virtual desktop snapshot information using ID information among terminal information regardless of the snapshot processing information.

Next, the management server 30 determines whether the ID information among the terminal information is shared ID information (S150), and when the ID information is the shared ID information, a logoff request signal to terminate the use of the virtual desktop from the user terminal 11 It is possible to initialize the virtual desktop snapshot information without storing the virtual desktop usage information used by the corresponding user terminal 11 based on the virtual desktop information at the time when is received (S160).

On the other hand, the management server 30 determines whether the ID information among the terminal information is shared ID information (S150), and if the ID information is dedicated ID information (S170), the management server 30 is a virtual desktop from the user terminal 11 When the logoff request signal for terminating the connection is received, the corresponding virtual desktop usage information is stored as the latest virtual desktop usage information based on the virtual desktop information (S180), and then the virtual desktop snapshot information may be initialized ( S160).

5 is a detailed flowchart illustrating a method of reallocating a virtual desktop to a user terminal in a virtualization system that initializes virtual desktop snapshot information according to an embodiment of the present invention.

Referring to FIG. 5, the management server 30 may receive terminal information and a virtual desktop reallocation request signal of the user terminal 11 transmitted from the user terminal 11 included in the user terminal group 10 ( S14).

Next, the management server 30 may receive the virtual desktop information from the virtual desktop (VD) that has been assigned to the user terminal 11 (S35).

Next, the management server 30 reallocates the virtual virtual desktop (VD) storing the latest virtual desktop snapshot information to the user terminal 11 based on the terminal information, the virtual desktop reassignment request signal, and the virtual desktop information. It can be (S36).

Finally, the user terminal 11 can execute the reassigned virtual desktop (VD) from the management server 30 (S15).

The described embodiments may be configured by selectively combining all or part of each embodiment so that various modifications can be made.

In addition, it should be noted that the embodiments are for the purpose of explanation and not for the limitation. In addition, a person skilled in the art of the present invention will understand that various embodiments are possible within the scope of the technical idea of the present invention.
