Ever tried to mount a partition that is inside an image with multiple partitions? With kpartx of the multipath-tools package, it's really easy. It scans the image and creates a individual device file for every partition using the device mapper.

Example in case of a KVM image: http://blog.piotrj.org/2009/03/mounting-raw-kvmqemu-image.html

First create a loop device for the image:

losetup -f /path/to/image

Then create a vmdk file for the resulting loop device:

VBoxManage internalcommands createrawvmdk -filename my_image.vmdk -rawdisk /dev/loop/0

This vmdk file can be used by Virtualbox as a hard disk.
