Title:
VIRTUAL MACHINE CONTAINER APPARATUS, CONTROL METHOD OF VIRTUAL MACHINE CONTAINER, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2023064327
Kind Code:
A
Abstract:
To provide a virtual machine container apparatus which can execute a container for an OS different from a host OS in a container-based virtualization environment.SOLUTION: In a virtual machine container apparatus 10, a virtual machine monitor unit 12 acquires a system call generated by a process of an application loaded to a virtual machine container unit 11. A system call control unit 13 determines whether an OS of the application and an OS of a host OS kernel unit 14 are the same or not, using the system call acquired by the virtual machine monitor unit. When a determination is made that the OSs are the same, the host OS kernel unit 14 executes the system call, and returns an execution result to the process. When a determination is made that the OSs are different from each other, an OS kernel emulation unit 15 emulates the system call in accordance with the OS of the application, and returns an execution result of the emulation to the process.SELECTED DRAWING: Figure 1
