Sorry, I'll do it tomorrow. I've been debugging some horrible utilities to automate a bunch of forum stuff. Alternately can't you just upload it as an attachment?

1) Get the package nbd:
On Ubuntu:

Code: Select all

apt-get install nbd-client

2) Compile it
Download it, compile it with:

Code: Select all

gcc vdimount.c -o vdimount -pthread -l:/path/to/virtualbox/VBoxDD.so -Wl,-rpath,/path/to/virtualbox -I/path/to/includes/for/virtualbox

I've installed nbd-client and run '' gcc vdimount.c -o vdimount -pthread -l:/usr/lib/virtualbox/VBoxDD.so -Wl,-rpath,/usr/lib/virtualbox -I/usr/bin '' (according to my installation of VirtualBox).
It ends with following error message: '' gcc: vdimount.c: No such file or directory ''
I allready expected this error message, because how should gcc know of any vdimount.c ? I don't know where I could find this vdimount.c (I searched all /usr for this file, no where).

Anybody an idea?

Thanks, Ulrich

Is it possible to mount the VDI file automatically at the system startup?
for example using /etc/fstab, etc.?

Thanks

Sorry for making everyone wait; heres the next version!

Works perfectly. Compile with no errors, mont XP and Windows 7 Images.

That *must* be a Feature of VBOX in the Original Version.

Thanks h₂o. The attachment idea is far better than relying on me. Sorry. A fantasic job. Well done

I've compiled vdfuse50.c without errors.
In /etc/fuse.conf, I have uncomment 'user_allow_other'
/dev/fuse has chmod 20666
/mnt/loop/ is rw for any user.

When I try to mount the DVI with following command: vdfuse -t VDI -v -f /media/sda2/VirtualBox/HardDisks/WindowsXP.vdi /mnt/loop/

I receive as error:
. fusermount:
. failed to open /etc/fuse.conf: Permission denied
. fusermount: option allow_other only allowed if 'user_allow_other' is set in /etc/fuse.conf
Which is strange, since I've uncomment it.

When I try to do this as root, I get error message:
. Partition Size Offset
. ========= ==== ======

. Partition1 32256 10725732864


. fuse: mount failed: Invalid argument

Strange, isn't it?

Furthermore: does some HOWTO exist, where everything is explained?

Thanks for any help.

Check the permissions on /etc/fuse.conf.

I changed the permissions of /etc/fuse.conf.

Now I can use vdfuse, which gives me two files: EntireDisk and Partition1. I have to use the latter, but then I receive the error:
# mount -o loop /mnt/loop/Partition1 /mnt/iso/ -t ntfs
/mnt/loop/Partition1: No such file or directory

I read on this thread that vdfuse.c has to be patched, but that fails with the error:
patch: **** malformed patch at line 16: @@ -104,7 +104,11 @@ (as allready was mentioned)
I use Kubuntu 8.10 (Linux)

Did you use this version? http://forums.virtualbox.org/viewtopic. ... 225#p75225

Yes, vdfuse50.c

The latest version doesn't need patched. If you are mounting the VDI on /mnt/loop then what do you see when you do a

• ls -l /mt/loop
  file /mnt/loop/Partition1

The problem seems to be solved (more or less).

I've vdfuse'd the VDI to another directory, and now I can mount Partition1.
The directory which fails AND the one which succedes are owned by the user (Ulrich) and have permissions set: dr-xr-xr-- (octal: 40554).
Partition1 in both directories has octal: 10644


ulrich@Phaedon:~$ ls -l /mnt/loop
insgesamt 20960109
-rw-r--r-- 1 ulrich ulrich 10737418240 2009-05-10 23:06 EntireDisk
-rw-r--r-- 1 ulrich ulrich 10725732864 2009-05-10 23:06 Partition1

ulrich@Phaedon:~$ file /mnt/loop/Partition1
/mnt/loop/Partition1: writable, regular file, no read permission

root@Phaedon:~# mount -o loop /mnt/loop/Partition1 /mnt/iso/ -t ntfs
/mnt/loop/Partition1: No such file or directory

Strange and important detail: when I try to open/read Partition1 with MC, I also receive a 'no such file or dierectory'.

Now I've vdfuse'd to /mnt/iso:
ulrich@Phaedon:~$ ls -l /mnt/iso
insgesamt 20960109
-rw-r--r-- 1 ulrich ulrich 10737418240 2009-05-11 12:58 EntireDisk
-rw-r--r-- 1 ulrich ulrich 10725732864 2009-05-11 12:58 Partition1

ulrich@Phaedon:~$ file /mnt/iso/Partition1
/mnt/iso/Partition1: x86 boot sector, Microsoft Windows XP Bootloader NTFS (german) (!!!!!!!!!!!!!!!!???!!!!!!!!!!!!!!!!!!!!!!)
Mounting as loop device works now.

Does vdfuse not like directories that are named 'loop'?

Is it also possible to mount snapshots this way?
I have a corrupt virtual machine, and would like to retrieve information that must be stored inside a snapshot.
When I try to do so, I receive as error: ERROR: opening vbox image failed

Unfortunately this version doesn't support snapshots. I have no idea why because I have no idea what a snapshot is composed of. Maybe Terry would know why...
