$ sudo mount vmware-server-flat.vmdk /tmp/test/ -o ro,loop=/dev/loop1,offset=32768 -t ntfs
Mount a VMware virtual disk (.vmdk) file on a Linux box
Assumes XP/2000/2003. For Server 2008+ try offset=105,906,176 You can find this number in the System Information utility under Partition Starting Offset. UEFI based boxes you want partition 2 since the first is just the boot files (and FAT). This works with (storage side) snapshots which is handy for single file restores on NFS mounted VMware systems
$ kpartx -av <image-flat.vmdk>; mount -o /dev/mapper/loop0p1 /mnt/vmdk
This does not require you to know the partition offset, kpartx will find all partitions in the image and create loopback devices for them automatically. This works for all types of images (dd of hard drives, img, etc) not just vmkd. You can also activate LVM volumes in the image by running
vgchange -a yand then you can mount the LV inside the image.
To unmount the image, umount the partition/LV, deactivate the VG for the image
vgchange -a n <volume_group>then run
kpartx -dv <image-flad.vmdk>to remove the partition mappings.
