Abstract

This paper explains how to obtain disk and volume information by using a virtual disk in the QEMU/KVM environment of the Linux operating system. In some cases, one may require disk and volume information for a specific virtual disk. To enable this, we designed a function for obtaining disk volume information by using the libguestfs API, and reported disk volume information results for a specific virtual disk file. Keywords—component; QEMU, KVM, Hypervisor, Libguestfs, Qcow2

基于qemu的虚拟化中的磁盘信息获取研究
本文介绍了如何在Linux操作系统的QEMU/KVM环境下使用虚拟磁盘获取磁盘和卷信息。在某些情况下,可能需要特定虚拟磁盘的磁盘和卷信息。为此,我们设计了一个函数,通过使用libguestfs API获取磁盘卷信息,并报告特定虚拟磁盘文件的磁盘卷信息结果。Keywords-component;QEMU、KVM、Hypervisor、Libguestfs、Qcow2
