Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] The method of the present invention is a Linux VMware virtual machine disk file (VMDK) access method on the Windows platform, and the scheme includes a loading program for the Linux virtual machine disk and a driver program for ext2 / ext3 file system analysis. The mount program can be developed independently or by using the VMware Mount Utility tool provided by VMware to create a virtual volume by using the VMDK file in the host operating system to provide the user with a new logical disk drive letter. The implemented ext2 / ext3 file system analysis creates a device object to the I / O manager of the Windows kernel, and registers the file system, so that the Windows operating system can access file systems other than FAT, NTFS, CDFS, and UDF. ...

Abstract

The invention discloses a file access method of a Linux virtual machine disk under a Windows platform, which comprises a mount program for the Linux virtual machine disk and a drive program for an ext2 / ext3 file system analysis. The file access method is characterized in that the mount program uses a VMware Mount Utility tool provided by the VMware company, creates a virtual volume by using a VMDK (Virtual Machine Disk Format) file in a host operating system and provides a new logic disk letter for a user; the realized ext2 / ext3 file system analysis creates a device object to an I / O manager of a Windows kernel and registers the file system so that the Windows operating system can access file systems besides FAT, NTFS, CDFS and UDF; and the drive program is installed in the catalog of \Windows\system32\drivers and is used by the Windows host (including but not limited to) operating system to analyze a file system in ext2 / ext3 format.

Description

Technical field: [0001] The invention relates to computer forensics and virtualization technology, in particular to a Linux virtual machine disk file access method under the Windows platform. Background technique: [0002] VMware is a company that develops and sells computer virtualization products. Its virtualization software widely adopts the Virtual Machine Disk (VMDK) format as its standard virtual machine disk file format. The operating system, applications, and user files required by the virtual machine to run are stored on this virtual disk. VMware's virtual desktop product, VMware Workstation, can run multiple virtual machines (Windows, Linux, etc.) on a host operating system (such as Windows). [0003] In computer judicial forensics, the object of forensics may be the disk file of the Linux virtual machine. There are usually two methods to access the disk file of the virtual machine: the first type is to start the VMware virtual machine software and access the virt...
