vboximg-mount is a command line utility for Mac OS and Linux hosts that provides raw access to an virtual disk image on the host system. Use this utility to mount, view, and optionally modify the disk image contents.

The utility is based on Filesystem in Userspace (FUSE) technology and uses the VirtualBox runtime engine. Ensure that is running on the host system.

Raw access using FUSE is preferred over direct loopback mounting of virtual disk images, because it is snapshot aware. It can selectively merge disk differencing images in an exposed virtual hard disk, providing historical or up-to-date representations of the virtual disk contents.

vboximg-mount enables you to view information about registered VMs, their attached disk media, and any snapshots. Also, you can view partition information for a disk image.

The vboximg-mount command includes experimental read-only access to file systems inside a VM disk image. This feature enables you to extract some files from the disk image without starting the VM and without requiring third-party file system drivers on the host system. FAT, NTFS, ext2, ext3, and ext4 file systems are supported.

Use the --help option to view information about the vboximg-mount command usage. The complete command reference is described in .

When vboximg-mount mounts an disk image, it creates a one level deep file system at a mount point that you specify. The file system includes a device node that represents the synthesized disk image as a readable or readable-writeable bytestream. This bytestream can be mounted either by using the host OS or by using other FUSE-based file systems.
