I tried your technique and it works for me. But I wanted to save the pain of having to go to the terminal and eventually create mountpoins for my partitions, so I was hoping ‘partprobe’ to allow me to handle the nbdXpY volumes through nautilus…
Should it work?
When I run partprobe, I get this error:

I searched google all night to figure out how to mount a dynamic vdi image, and this worked like a charm. Most other methods required finding the data offset number, or didnt work right with dynamic images (for example, after I finally figured out the correct offset number, I kept getting a "Failed to read last sector" error for an ntfs filesystem trying to mount it with a /dev/loop0). I did have to use the "max_part" option as listed in the above post. For clarity and to help others, the following worked for me on openSuse 11.4 - 64bit host, mounting an ntfs filesystem from a dynamic vdi created from a virtualbox windows7 guest: 1) unload network block devicei kernel module, in case it is loaded without the max_part option (if you have already linked any nbd devices to vdi files, remove them with "qemu-nbd -d /dev/nbd0" or similar) <code> rmmod nbd </code> 2) reload nbd with max_part option <code> modprobe nbd max_part=16 </code> 3) link your nbd to your vdi file <code> qemu-nbd -c /dev/nbd0 VDIFILE.vdi </code> 4) scan for partitions, this should create the new device files in dev <code> partprobe </code> 5) list your device files to make sure they were created <code> ls -l /dev/nbd0* </code> 6) to view the sizes of any partions found in the vdi, you can run fdisk and print the partition table <code> fdisk /dev/nbd0 p </code> 7) finaly, mount the desired partition (I used '-r' for readonly to be safe) <code> mount -t ntfs -r /dev/nbd0p2 /MNTPOINT </code> Woohoo!!!

For clarity and to help others, the following worked for me on openSuse 11.4 – 64bit host, mounting an ntfs filesystem from a dynamic vdi created from a virtualbox windows7 guest:

1) unload network block devicei kernel module, in case it is loaded without the max_part option (if you have already linked any nbd devices to vdi files, remove them with “qemu-nbd -d /dev/nbd0″ or similar)

rmmod nbd

2) reload nbd with max_part option

modprobe nbd max_part=16

3) link your nbd to your vdi file

qemu-nbd -c /dev/nbd0 VDIFILE.vdi

4) scan for partitions, this should create the new device files in dev

partprobe

5) list your device files to make sure they were created

ls -l /dev/nbd0*

6) to view the sizes of any partions found in the vdi, you can run fdisk and print the partition table

fdisk /dev/nbd0
p

7) finaly, mount the desired partition (I used ‘-r’ for readonly to be safe)

mount -t ntfs -r /dev/nbd0p2 /MNTPOINT

(I'm tasked with writing an article about that in the GNOME Annual Report.) Little did I know, I would get to read such authentic post as this. Your understanding of depression as an internal force, and your willingness to take responsibility and follow the "steps" out of this darkness is so inspiring. Thank you so very much. Jeff-
