not sure it's true as vb can use raw disks, vdfuse do just what I
said, as you have the vdfuse sources you can guess where is the
offset. either it's constant or there is a pointer to the disk on the
very first bytes of the file. using the vb library is probably
mandatory for variable size disks where data is stored in various
locations
vdfuse:
DESCRIPTION: This Fuse module uses the VirtualBox access library to
open a VirtualBox supported VD image file and mount it as a Fuse file
system. The mount point contains a flat directory containing the
files EntireDisk, Partition1 .. PartitionN. These can then be loop
mounted to access the
underlying file systems
USAGE: vdfuse [options] -f image-file mountpoint
-h help
-r readonly
-t specify type (VDI, VMDK, VHD, or raw; default: auto)
-f VDimage file
-a allow all users to read disk
-w allow all users to read and write to disk
-g run in foreground
-v verbose
-d debug
NOTE: you must add the line "user_allow_other" (without quotes)
to /etc/fuse.conf and set proper permissions on /etc/fuse.conf
for this to work.
