It’s ridiculously easy and simple to open the native to VMware virtual machine VMDK file in VirtualBox. For a reference, VMDK is as an abbreviation for Virtual Machine Disk, - it’s a format of the file, which is applied for virtual applications designed for VMware products. Despite the following methodic is described in many tutorials, actually in order to open VMDK file on VirtualBox you don’t need to convert it into a VDI-file object. Below I will explain the detailed procedure of opening this object on ordinary VirtualBox instance.
- start creating the new virtual machine instance as usually, by clicking the New button in VirtualBox Manager.
- enter the name of your VM and choose the OS you would prefer to use. In my case this is Linux, but your choice belongs only to you, so it can be any OS from Windows to FreeBSD and Mac OS, depending on your selection.
- define the amount of RAM-memory which you would like to have for your virtual machine. The more RAM you set, the faster your virtual environment would work, but don’t forget, that actually this space will be physically reduced from your host OS, so make a reasonable decision while selecting the appropriate amount of space for your virtual environment.
- at this moment you will be asked for virtual hard disk creation. This iteration is crucial in running your VMDK-file object in VirtualBox. Pick the menu item “Use existing hard disk” and after that make a click on the “Choose a virtual hard disk file” pictogram on the right part of the form.
- now the file selection dialogue form appears. In here you need to open up, browse and choose the VMDK file object which you would like to open.
- after the file is found on the HDD-storage and selected, click Open button.
- from now in the “Use existing hard disk” menu item the selected VMDK-file will be defined. Click Next button afterwards.
- at last, when all the previous stages are completed, click the Create button. On this particular iteration the virtual machine instance will be initialized and created, so the procedure of attaching the VMDK image is over.
- since that moment the new VM-instance will be listed in the VirtualBox Manager. Click the “Start” button, and the VM will run.
The other way to run VMDK file on VirtualBox application is to preliminarily convert the VMDK file object in to VDI – the format, native to this VM environment. If you are going to use this method, you will need to address to external VBoxManage utility, which is included into the VirtualBox package. This tool is entirely console, so all the commands in it are entered via command line. In order to learn how to use the VBoxManage services, address to the official documentation.
So this is, basically, the way, how to run VMware image in VirtualBox. As you can see, the methodic is absolutely intuitive and straightforward, so you will quickly get used to it and will be able to handle the external formats like a piece of cake.
So you’re running Linux on your computer, maybe Ubuntu, and you have some files with the .dmg extension. In this guide, we’re going to talk about how to open, mount, extract, and otherwise get your files from these pesky DMG images. You could always just extract the files on a Mac, then transfer them back to your Linux machine. But if you really want to do this on Linux, without having to rely on Mac, here’s how to do it.
What are DMG image files?
Simply put, it’s a kind of image file. But not an image like a jpeg is an image. DMG is Apple’s proprietary disk image format, native to Mac OS X. There are actually a whole bunch of different types, format and options within this format. There are options for encryption, compression, and different kinds of partition schemes, among others. Unfortunately, this can make things pretty confusing when we’re trying to gain access to the data contained in one of these images.
DMG images are typically a kind of Universal Disk Image Format (UDIF), although there are others, namely NDIF and SPARSE. Although the .dmg file extension is usually used, they can also sometimes have an .img extension, or in some cases no extension at all. Their MIME type is application/x-apple-diskimage.
The HFS/HFS+ (Mac OS Extended/Journaled) file system is typically used in DMGs. However, this isn’t always the case. You may also sometimes find FAT and ExFAT files systems, as well as variations on HFS.
Does my system support DMG?
Perhaps the biggest hurdle to overcome when trying to work with DMG files is working with the HFS file system (Mac OS Extended). Linux supports HFS through the “hfs” and “hfsplus” kernel modules.
There’s an easy way to test if your system has these kernel modules. Plug in a USB drive formatted with the Mac OS Extended file system. If your particular distribution doesn’t have the appropriate modules, you will likely get an error message. On Ubuntu, you’ll get a popup window declaring “Ubuntu: Unable to mount
Open Dmg Files In Virtualbox
Alternatively, we can see if the kernel module files are present with find:

We want to see two files: “hfs.ko” and “hfsplus.ko”. If find doesn’t return these files, your system probably doesn’t support HFS.
You could also try “modinfo”: modinfo hfs and modinfo hfsplus should return something like:
If you get 'modinfo: ERROR: Module hfsplus not found' your system doesn’t have these modules.
Not all Linux kernels and distributions support HFS. This is especially the case for certain distributions that are a few years old. If you have kernel support for HFS, great! If not, don’t worry. There are still ways to extract data from your DMG files. While it’s nice to have the option to mount the images we’re working with, this is really the only functionality we’re losing without having the hfs and hfsplus modules. The two programs we’re going to use later on (P7ZIP and dmg2img) do not require kernel support to function.
What kinds of DMG images can be opened in Linux?
This guide is about how to open, mount, and extract files from read/write, read only, and compressed DMG image files. The following partition schemes have all been tested with the techniques discussed here.
- Apple Partition Map
- CD/DVD (partitioned)
- CD/DVD (partitioned) with ISO data
- Hard disk
- Master Boot Record Partition Map
- No partition map
This guide does not cover how to handle sparse disk images (.sparseimage), sparse bundle disk images (.sparsebundle), or CD/DVD masters. DMG images with partition scheme types of “CD/DVD” and “GUID Partition Map” do not appear to work with the techniques described here.
Option 1: Mount the DMG
Open Dmg Files In Virtualbox Download
If the Linux distribution you’re on has HFS support in the kernel (Ubuntu 14.04.1 LTS supports it), it’s pretty easy to just mount the DMG image:
We’re using “sudo” because we need root privileges to mount things. The HFS+ file system type is specified with “-t hfsplus”. The “/mnt” at the end of the command specifies where we’re mounting the image.
Unmount the image with sudo umount /mnt
If you get a wrong fs type message like the one below, it means the DMG file is either of an unsupported type, or it’s compressed. Unsupported images include sparse images, sparse disk bundles, CD/DVD masters, and images with partition schemes of the CD/DVD or GUID Partition Map types.
Use “file” to learn a little more about the image file:

If you get image.dmg: x86boot sector that means it’s probably using a GUID Partition Map and isn’t supported. This isn’t good, however, it’s also not too terribly common.

What’s more common is to see something like this:
If mounting isn’t working, and this is what you’re seeing with “file image.dmg”, then you’re luck!. Our problems are being caused by compression. Linux doesn’t like to mount compressed DMG images. To get around this little obstacle, we’ll use dmg2img (see below).
Option 2: Use dmg2img for compressed images
So you have a DMG image that you can’t mount because it’s compressed. You’ve done “file compressed_image.dmg” and you got “compressed_image.dmg: bzip2 compressed data”. The fix? That’s easy: use dmg2img to convert it to an uncompressed image. Once you run the image through dmg2img you should be able to mount it no problem.
Don’t have dmg2img? It’s usually pretty easy to get using your distribution’s package management. On Ubuntu, you’d do:
Using dmg2img isn’t very difficult. Type “dmg2img” into the command line followed by the name of the DMG file you want to decompress. The Mac OS X version of Firefox is a good example of a compressed DMG file.
Now mount the resulting .img file:
Option 3: Extract DMG contents with P7ZIP
P7ZIP is awesome. It’s the Linux/BSD version of 7-Zip. Check out their SourceForge page here With it you can literally extract files from any kind of image or archive. Just kidding… It doesn’t really work with every format conceivable. However, it can handle (in alphabetical order): ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR and Z. Impressed? I certainly am!
Installing p7zip is pretty easy using your distribution’s package management system. On Ubuntu with apt-get:
In addition to being able to extract data from compressed and uncompressed images alike, P7ZIP doesn’t require the HFS kernel modules at all. In the example below, we’re going to extract all of the files from “Firefox 33.1.1.dmg”. When we’re done, we’ll have a tidy little folder called “Firefox”.
Invoke P7ZIP to extract archives and images with “7z x”.

Notice that 7z extracted three files: “0.ddm”, “1.Apple_partition_map”, and “2.hfs”. To actually get to the files, we’ll need to run 7z again on “2.hfs”.
We picked “2.hfs” because it was the biggest of the three, meaning it was probably the one with the data. Simple but effective logic. After a few moments, you should have a folder called “Firefox” with all of the files from the original DMG.
