Is it still possible to mount VMWare disk images under Linux?

I found the following two articles, both of them recommend to use kpartx -av diskimage-flat.vmdk. However both the articles are old and, when I try it on my Ubuntu Utopic 14.10, it no longer works any more.

$ sudo kpartx -av MyWin81.vmdk

$ sudo ls /dev/mapper/loop* | wc -l 
ls: cannot access /dev/mapper/loop*: No such file or directory
0

Disclosure: My VMWare disk image IS a flat disk image. Furthermore (before you recommend loop mount), it is a multi-partition disk image, with first partition being Window8 and next two in Linux. It is the next two Linux partitions that I'm more interested to work on.

Can someone confirm please? Thanks.

UPDATE:

vmware-mount looks very promising, but I can't get it working yet:

$ vmware-mount -p Win81.vmdk

NB, the 2nd and 3rd command is run directly as root, yet I get "Insufficient permissions to perform this operation"?

You can also use qemu:

For .vdi

sudo modprobe nbd
sudo qemu-nbd -c /dev/nbd1 ./linux_box/VM/image.vdi

if they are not installe you can install them (on Ubuntu is this comand) 

sudo apt install qemu-utils

and then mount it 

mount /dev/nbd1p1 /mnt

For .vmdk

sudo modprobe nbd
sudo qemu-nbd -r -c /dev/nbd1 ./linux_box/VM/image.vmdk

notice tha I use the option -r that's because VMDK version 3 must be read only to be able to be mounted by qemu

and then I mount it 

mount /dev/nbd1p1 /mnt

I use nbd1 because nbd0 sometimes gives 'mount: special device /dev/nbd0p1 does not exist'

For .ova

tar -tf image.ova
tar -xvf image.ova

The above will extract the .vmdk disk and then mount that.

My configuration:

Ubuntu: 16.04.3 LTS 
Kernel: 4.4.0-112-generic  
Package: qemu-utils version: 1:2.5+dfsg-5ubuntu10.22 
Vmdk: 3 but should be any

    Thanks Eduard. Please let people know what OS your machine is on, e.g., run `lsb_release -a` and/or `uname -a`, and tell us the version of `qemu` and `vmdisk` that you are using now, then post back the results. – xpt Feb 27 '18 at 03:39

    works with `qemu-nbd 2.12.0 ` on Arch Linux - I had to skip using `-r` for a file on a filesystem mounted `ro` – Stuart Cardall Jul 08 '18 at 18:53

Install affuse, then mount file with it:

affuse /path/file.vmdk /mnt/vmdk

Check sector size

fdisk -l /mnt/vmdk/file.vmdk.raw

# example

Disk file.vmdk.raw: 20 GiB, 21474836480 bytes, 41943040 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x000da525

Device       Boot Start      End  Sectors Size Id Type
/mnt/vmdk/file.vmdk.raw1 *     2048 41943039 41940992  20G 83 Linux

Multiply sectorsize and startsector. In example it would be 2048*512

echo 2048*512 | bc
1048576

Mount using that offset

mount -o ro,loop,offset=1048576 /mnt/vmdk/file.raw /mnt/vmdisk

Disk should now be mounted and readable on /mnt/vmdisk

In my machine the loop devices are in /dev. This article mentions /dev/wrapper and /dev, so it could be of help to you.

On the other hand, this other article uses the vmware-mount command to accomplish the same.

Note: My system is Slackware64-current (mostly), but with mainly gtk-based software.

  • Just another idea: It seems Virtualbox recognizes `vmdk` images. So maybe the remark from sehams on your original question is not as farfetched as it seemed to me. If you install VB, you could possibly use `vboxmanage` to convert, then just `mount` it with `loop` device. – jcoppens May 17 '15 at 15:02
