Linux open vdi file

Is there any way to extract content of .vdi file?

I am having Ubuntu as a Host machine and Windows VM. The VM is not starting. I need to take some important files from the virtual machine to Host Machine. So is there any way to extract the contents of Windows VM without running it?

Check out the answers to this question. There are three solid options. Hopefully one of them works for you 👍🏻

P7Zip will open VDI files

• Install P7Zip-Desktop from Ubuntu Software.
• Open folder containing VDI file in Nautilus, (Files).
• Right click VDI file and select Open with Other Application .
• Select P7Zip Desktop.
• Double click the VDI file in the P7Zip window.
• View or extract files as you like.

If you are using Windows-10, you can use 7-Zip to extract vdi files.
Its an opensource and free software and very easy to use.

• Download the software
• Navigate to the your vdi file.
• Double click on the vdi file
• In my case, I saw files like 0.fat, 1.img
• Check the file type and size to determine which file you want to open.
• Double click on the file. I double clicked on 1.img because that was my device.
• Wait for few minutes.
• When the process is complete, you will see the complete filesystem.
• Now you can easily copy files to you windows drive.

How to Mount VirtualBox Disk Image (VDI) to Access VM File-System in Ubuntu

This tutorial shows how to mount the VirtualBox virtual disk image in Ubuntu, so you can access the Guest OS file system with read and write permission, if it does not boot.

After misconfigured my VirtualBox Guest OS, it does not longer work. I know how to correct the issue to make it boot again, but firstly accessing to the file system is required!

Since the VBox user manual does not work, here’s what I did in Ubuntu 20.04 host with VirtualBox 6.1.x:

Before getting started, make sure Guest OS is shutdown. And the disk image is not in use. Also UN-MOUNT the disk once the job done.

1.) Firstly open terminal from system application launcher. When it opens, run command:

vboximg-mount is a utility to make VBox disk images available to the host. With —list , it list all Disk Images as well as the UUID.

In the case, I have all Guest OSes on single Disk Image (.vdi). And the uuid is: “3db5fd91-fd56-46af-a2d2-98cd62b05ea3”

2.) Next perform a FUSE mount of the virtual disk image:

First create a folder as mount point, vbox_sysdisk for instance:

vboximg-mount -i 3db5fd91-fd56-46af-a2d2-98cd62b05ea3 -o allow_root vbox_sysdisk

NOTE: You may need to edit the “/etc/fuse.conf” to make the -o allow_root flag work. To do so, run command sudo gedit /etc/fuse.conf and enable (remove # at its beginning) “user_allow_other” line.

3.) As the previous picture shows, I have 5 disk partitions: vol0, vol1, …, vol4. Now mount either partition (vol4 for instance) to /mnt via command:

sudo mount vbox_sysdis/vol4 /mnt

Finally go to /mnt directory and there you are.

Unmount:

To un-mount the guest os file system, run command:

To un-mount the VBox disk image, run command:

And you may finally remove that folder either from file manager or by running command in terminal:

Mounting/opening virtualbox disk image (vdi) on linux host

Is it possible to mount vdi like for example iso? Or open it with some archive program? If yes, how? edit: My vdi is dynamically expanding storage and i have snapshots too.

Is this the subset of a larger problem? Are you trying to access data for a VM you don’t want to start for some reason? If it is running and you to access the data, some sort of file sharing from the VM is probably the best solution.

For both fixed and dynamic-sized images:

On Linux you can use qemu-nbd . On Debian it’s in the qemu-tools package. It’s likely in a similar package for other distros. It will let you mount any disk image recognised by qemu, which includes VDI.

Install it, modprobe nbd to make sure it’s loaded, then do a qemu-nbd -c /dev/nbd0 to make it available. It will show up as /dev/nbd0p? for each of the partitions in the image unless told to do otherwise. See the man page for further details.

When finished, a qemu-nbd -d /dev/nbd0 will detach it.

Be sure you don’t have it attached in multiple places at once! This WILL cause problems!

Tool for fixed size Disk Drives:
It can be done with static vdi images (Fixed Size, not dynamically expanding). It is a matter of finding the offset in the image where the partition starts.

Here is page that has a shell script that automates the process for you.

If Dynamic:
Method 1
If you are using a dynamically size image, convert it to a fixed size image (make sure you have the HD space) and then use the above tool (reference):

vditool COPYDD myDynamicDisk.vdi static_dump.vdi 

Method 2
Reading up it seems vditool is no longer included. A simple way to create the partition image would be to use gparted iso as a boot disc inside of the Virtualbox VM to create the image of the partition to a location on your network, and then mount that image.

Fuse Module:
There is also a fuse file system for this called vdimount that does this, but I am not sure how well it works.

How can i Extract Files From VDI

I was using VirtualBox on my PC(WIN 7) I managed to View some files in my .VDI file.. How can I open or view the contents of my .vdi file and retrieve the files from there?

You can create a raw copy of the VDI through VBoxManage clonehd input.vdi output.block —format=raw . The next step if to find a way to map the raw block so its partitions can be mounted.

I had a corrupted VDI file (according to countless VDI-viewer programs I’ve used with cryptic errors like invalid handle, no file selected, please format disk) and I was not able to open the file, even with VirtualBox. I tried to convert it using the VirtualBox command line tools, with no success. I tried mounting it to a new virtual machine, tried mounting it with ImDisk, no dice. I read four Microsoft TechNet articles, downloaded their utilities and tried countless things; no success.

However, when I tried 7Zip (https://www.7-zip.org/download.html) I was able to view all of the files, and extract them selectively. Here’s how I did it:

• install 7zip (make sure that you also install the context-menu items, if prompted.)
• right-click on the VDI file, select «Open Archive»
• when the window appears, right click on the largest file in the archive (there should be two files, one is «Basic Microsoft Data Partition» and the other one something else, called system or something.) Left click on the largest one and click «Open inside». The file size is listed to the right of each file in bytes.
• you should see all of the files inside of the archive. You can drag files that you’d like to extract right to your desktop. You can double click on folders to view inside them too.

If 7zip gives you a cryptic error after extracting the files, it means that you closed the folder’s window that you are copying files to in Windows Explorer.

If you didn’t close the window and you’re still getting an error, try extracting each sub-folder individually. Also make sure that you have enough local hard drive space to copy the files to, even if you are copying them just to an external disk, as 7zip copies them first to your local disk. If the files are highly compressible, you might be able to get away with using NTFS compression for the AppData/temp folder so that when 7zip extracts the files locally, it’ll compress them so that it can copy them over to your other disk.
