Description

Hypervisor system and hypervisor operation method {HYPERVISOR SYSTEM AND OPERATING METHOD OF HYPERVISOR}

Embodiments of the present invention relate to hypervisor technology.

A hypervisor refers to a software virtualization platform for simultaneously executing multiple operating systems (OS) on a host computer. However, existing hypervisors can run multiple operating systems of the same processor, but have a problem in that they cannot run operating systems of heterogeneous processors.

That is, in the existing hypervisor, processors such as Windows and Linux based on X86 can run multiple operating systems of the same type, but different types of processor-based processors such as ARM, PowerPC, and MIPS I couldn't run the operating system.

On the other hand, the latest ICT (Information and Communications Technology) convergence infrastructure such as smart city includes devices supporting a plurality of different ISA (Instructure Set Architecture) in various services such as smart transportation service and smart energy service. That is, in an ICT convergence environment (eg, 5G Massive infrastructure environment such as a smart city), it is an environment in which various heterogeneous processors and operating systems (OS, RTOS) are executed.

In this ICT convergence environment, in order to collect and analyze various malicious codes and respond to malicious code intrusion, it is necessary to deploy traps similar to actual end devices, induce attacks, and detect them. However, since existing hypervisors cannot execute operating systems of heterogeneous processors, it is impossible to virtually build various types of device devices that support various heterogeneous processors and different ISAs.

In other words, since the virtual infrastructure that can be configured using the existing hypervisor is limited to X86-based Windows and Linux, traps for cyber security attack protection are deployed in the ICT convergence environment. However, there is a problem that the operating system is limited to X86-based Windows and Linux.

2 is a flowchart illustrating a method of operating a hypervisor according to an embodiment of the present invention. In the illustrated flowchart, the method is divided into a plurality of steps, but at least some of the steps are performed in reverse order, combined with other steps, performed together, omitted, divided into detailed steps, or not shown. One or more steps may be added and performed.

Here, an operating method for executing a heterogeneous command operating system in the hypervisor system 100 will be described as an example. To this end, the hypervisor system 100 creates a simulator 111, configures a heterogeneous virtual platform 112, and mounts it on the simulator 111.

Referring to FIG. 2 , when the hypervisor 110 is executed by a user's command in the host computer 50, the hypervisor 110 may call the hypervisor management tool 120 (S 101). At this time, the hypervisor 110 may call the hypervisor management tool 120 using a command method through a shell screen or call the hypervisor management tool 120 through a GUI (Graphic User Interface) program.

Next, the hypervisor management tool 120 may display the previously stored virtual platform support list on the screen of the host computer 50 (S103). That is, the hypervisor management tool 120 may display a list of virtual platforms supported by the host computer 50 on the screen.

For example, a virtual platform support list may be stored in the virtual platform library DB 115 . The hypervisor management tool 120 may extract a virtual platform support list from the virtual platform library DB 115 and display it on the screen.

Next, the hypervisor management tool 120 may check the command operating system related to the virtual platform selected by the user from the virtual platform support list (S105).

That is, the hypervisor management tool 120 determines whether the virtual platform selected by the user from the virtual platform support list is for executing a homogeneous instruction operating system (homogeneous virtual platform) or for executing a heterogeneous instruction operating system (heterogeneous virtual platform). platform).

In step S105, if the virtual platform selected by the user is a heterogeneous virtual platform, the hypervisor management tool 120 checks the heterogeneous virtual platform and extracts a library for the heterogeneous virtual platform from the virtual platform library DB 115. and can be transmitted to the hypervisor 110 (S 107). Here, the library may be a file including setting values of a memory, processor, bus, peripheral device, etc. for constituting a heterogeneous virtual platform.

Next, the hypervisor management tool 120 requests and receives a binary corresponding to the heterogeneous virtual platform selected by the user (ie, a binary to be executed in the heterogeneous virtual platform) from the virtual platform binary uploader 130 and receives the binary. It can be delivered to the hypervisor 110 (S 109).

That is, the virtual platform binary uploader 130 may store binaries corresponding to each virtual platform, and may upload binaries corresponding thereto to the hypervisor management tool 120 upon request from the hypervisor management tool 120. have.

Next, when the hypervisor 110 receives the libraries and binaries for the heterogeneous virtual platform, the simulator 111 for the heterogeneous virtual platform is operated by allocating resources to the heterogeneous virtual platform through the resource management tool 117. It can be created (S 111).

Here, the simulator 111 may be a layer for executing the heterogeneous virtual platform 112 described below while serving as an interface between the heterogeneous virtual platform 112, the hypervisor 110, and the hypervisor management tool 120. In addition, the resource management tool 117 monitors the X86-based hardware 200 and provides corresponding resources according to library setting values (eg, memory, storage space, CPU setting, etc.) of the heterogeneous virtual platform 112. can be assigned to heterogeneous virtual platforms.

Next, the hypervisor 110 may configure the heterogeneous virtual platform 112 based on the library for the heterogeneous virtual platform and mount it on the simulator 111 (S 113).

The heterogeneous virtual platform 112 may be configured through a library of virtual processors and virtual peripheral devices extracted from the virtual platform library DB 115 . The heterogeneous virtual platform 112 includes a virtual processor to drive software of an ISA (Instructure Set Architecture) different from that of the host computer 100 .

Next, the heterogeneous virtual platform 112 converts the uploaded binary into a command corresponding to the heterogeneous command operating system (A) and transfers it to the heterogeneous command operating system (A) to execute the heterogeneous command operating system (A). It can (S 115).

3 is a diagram schematically illustrating a configuration for command conversion in a heterogeneous virtual platform according to an embodiment disclosed herein. Here, it is assumed that the heterogeneous virtual platform 112 includes a virtual ARM processor 112a. The virtual ARM processor 112a may include an instruction interpreter 112a-1 and an instruction executor 112a-2. In this case, the uploaded binary may be an ARM binary.

The uploaded binary has a code area containing executable code, and this code area contains a series of instructions. The virtual ARM processor 112a sequentially imports each instruction included in the code region of the uploaded binary according to the execution flow, and identifies which instruction each instruction is in the instruction interpreter 112a-1. And, the virtual ARM processor 112a emulates the function of the corresponding command in the command executor 112a-2.

For example, when a 32-bit instruction is read from an ARM binary and the instruction interpreter 112a-1 identifies the instruction as an add instruction, the instruction executor 112a-2 recognizes the operand of the instruction ) form, the addition operation is performed, and the resulting value is stored in the register of the virtual ARM processor 112a.

Next, when the heterogeneous instruction operating system (A) is executed, the simulator 111 may obtain execution-related information executed in the heterogeneous instruction operating system (A) through the heterogeneous virtual platform 112 (S 117 ). Here, the execution-related information may include execution information (eg, execution codes, registers, memory, etc.) executed in the heterogeneous instruction operating system (A), execution binaries, and hardware setting values.

Next, the simulator 111 may transfer execution-related information executed in the heterogeneous command operating system A to the hypervisor management tool 120 (S 119).

Next, the hypervisor management tool 120 may convert the execution-related information into a preset binary format and store it in the execution binary DB 150 (S 121).

Next, the hypervisor 110 may sequentially terminate the simulator 111 and the heterogeneous virtual platform 112 and recover resources allocated to the heterogeneous virtual platform 112 (S 123).

4 is a flowchart illustrating a method of operating a hypervisor according to another embodiment of the present invention. In the illustrated flowchart, the method is divided into a plurality of steps, but at least some of the steps are performed in reverse order, combined with other steps, performed together, omitted, divided into detailed steps, or not shown. One or more steps may be added and performed.

Referring to FIG. 4 , when the hypervisor 110 is executed by a user's command in the host computer 50, the hypervisor 110 may call the hypervisor management tool 120 (S201).

Next, the hypervisor management tool 120, when the user tries to run the homogeneous command operating system through the homogeneous virtual platform, the virtual platform binary uploader (eg, X86 binary) corresponding to the homogeneous virtual platform 130), the binary may be transmitted to the hypervisor 110 (S203).

Next, the hypervisor 110 may create a dummy simulator 113 for the homogeneous virtual platform by allocating resources to the homogeneous virtual platform through the resource management tool 117 (S205).

Here, the dummy simulator 113 is to match the simulator 111 and the hierarchical structure, and can serve as an interface between the homogeneous virtual platform 114, the hypervisor 110, and the hypervisor management tool 120. That is, the dummy simulator 113 may have the same interface as the simulator 111 .

Next, the hypervisor 110 may configure the homogeneous virtual platform 114 and mount it on the dummy simulator 113 (S207). Here, since the homogeneous virtual platform 114 has the same command system as the host computer 50, it can be configured without a separate library, unlike when configuring a heterogeneous virtual platform. For example, the homogenous virtual platform 114 may be a virtual machine using Virtual Box, but is not limited thereto.

Next, the homogeneous virtual platform 114 may execute the homogeneous command operating system by transferring the uploaded binary (eg, X86 binary) to the homogeneous command operating system (S209). Here, since the uploaded binary has the same command system as that of the host computer 50, there is no need to convert the command unlike when executing a heterogeneous command operating system.

Next, when the execution of the homogeneous command operating system is terminated, the dummy simulator 113 may obtain execution-related information executed in the homogeneous command operating system through the homogeneous virtual platform 114 (S211).

Next, the dummy simulator 113 may transfer execution-related information executed in the operating system of the same command to the hypervisor management tool 120 (S213).

Next, the hypervisor management tool 120 may convert execution-related information into a preset binary format and store it in the execution binary DB 150 (S215).

Next, the hypervisor 110 may sequentially terminate the dummy simulator 113 and the homogeneous virtual platform 114 and recover resources allocated to the homogeneous virtual platform 114 (S217).
