Mount a VMware virtual disk (.vmdk) file on a Linux box

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 y and 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 then run $kpartx -dv to remove the partition mappings.
