Garfinkel and Basis Technology Corp. 1.0 What is xmount? - A short description xmount allows you to convert on-the-fly between multiple input and output harddisk image formats. xmount creates a virtual file system using FUSE (Filesystem in Userspace) that contains a virtual representation of the input image. The virtual representation can be in raw DD, Apple's Disk Image format (DMG), VirtualBox's virtual disk file format (VDI), Microsoft's Virtual Hard Disk Image format (VHD) or in VmWare's VMDK file format. Input images can be raw DD, EWF (Expert Witness Compression Format) or AFF (Advanced Forensic Format) files. In addition, xmount also supports virtual write access to the output files that is redirected to a cache file. This makes it for example possible to boot acquired harddisk images using QEMU, KVM, VirtualBox, VmWare or alike. 2.0 Input image support Starting with version 0.7.0, input image support has been moved into external libraries. The following chapters list the officially supported ones. They might not all be available on your system though. 2.1 libxmount_input_raw Supports raw DD images ("--in raw" or "--in dd"). 2.2 libxmount_input_ewf Supports EWF (Expert Witness Compression Format) images ("--in ewf") using Joachim Metz's libewf (https://code.google.com/p/libewf/). 2.3 libxmount_input_aewf Supports EWF (Expert Witness Compression Format) images ("--in aewf") generated with Guymager (http://guymager.sourceforge.net/). This library uses an EWF implementation written by Guy Voncken. It consumes much less memory than libewf when mounting big (>1TB) images. 2.4 libxmount_input_aff Supports AFF (Advanced Forensic Format) images ("--in aff") using Simson Garfinkel's afflib (https://github.com/simsong/AFFLIBv3). 2.5 libxmount_input_aaff Supports AFF (Advanced Forensic Format) images ("--in aaff") using an AFF implementation written by Guy Voncken. In essence, it is a lot faster than afflib. 3.0 Morphing support Also starting with xmount version 0.7.0, a new concept of input image morphing has been added. Morphing is a process which is applied to the data of all specified input images and produces a single virtual image which can then be converted into an output image. The following chapters list the currently officially supported morphing libraries. As with the input image libs, not all might be available on your system. 3.1 libxmount_morphing_combine Using "--morph combine", data from all input images is concatenated into a single image. Images are appended in the same order they are specified on the command line. This morphing type is also the default if no "--morph" option is specified. 3.2 libxmount_morphing_raid This morphing library supports emulation of hardware / software raid. Currently, only RAID0 ("--morph raid0") is supported. The used chunk / stripe size in bytes can be specified with "--morphopts raid_chunksize=XXX". All input images are treated as member disks of the original raid. 3.3 libxmount_morphing_unallocated Using "--morph unallocated" it is possible to extract unallocated sectors from a filesystem. For this to work, your input image must start with the volume you want to extract unallocated sectors from. If you have an image of a whole disk, you might need to use xmounts "--offset" parameter to move the start of the data to the start of the volume. Currently, unallocated sectors from HFS and FAT can be extracted. 4.0 Output image 4.1 Emulated RAW file This is the standard data representation used by xmount. It is a file containing the raw data contained in the input image file. Except for OSx - (see 2.2) this is the default output format when no --out option is + (see 4.2) this is the default output format when no --out option is specified. 4.2 Emulated DMG file This is also a file containing the raw data contained in the input image file but with a .dmg file extension. On OSx, this is the default output format when no --out option is specified. 4.3 Emulated VDI file When using the "--out vdi" command line parameter, a VirtualBox disk file is emulated. This means that xmount builds a virtual VDI header and prepends it to the raw data contained in the input image. The VDI file can be used in VirtualBox as a virtual disk file. 4.4 Emulated VMDK file When using the "--out vmdk(s)" command line paramter, a VMWare virtual disk file will be emulated. This mainly consists in building a VMDK descriptor file that will access an emulated RAW file. You can use this VMDK file to add your input image as virtual disk to a VMWare virtual machine. "vmdk" is a VMWare disk attached to the IDE bus and "vmdks" is attached to the SCSI bus. When emulating VMDK files to be used in VMWare, you have to enable "user_allow_other" in /etc/fuse.conf or run xmount and VmWare as root. WARNING: VMDK support should be considered experimental and currently the VMDK descriptor file isn't cached. 4.5 Emulated VHD file When using the "--out vhd" command line parameter, a Virtual Hard Disk Image file is emulated by appending to the raw data a valid VHD footer. Valid here means as described in Microsoft's Virtual Hard Disk Image Format specs v1. 5.0 Virtual write access By using the "--cache " command line parameter, xmount allows you to change data in the emulated image files. All changes are written to a separate cache file. No data will ever be written to the original input image files! Write access is limited to change existing data. It isn't possible to change the emulated image's file size (no append or truncate)! The same cache file can be used with different output image formats without loosing changed data. 6.0 Installation instructions To install xmount, you can use a prebuild package for your distribution or you can build xmount from source. The two methods are described in the following sections. 6.1 Prerequisits SYSTEM: - Linux: Some sort of Linux with a recent kernel (2.6.x or above). - OSx: OSx 10.6 or above FUSE: - Your os must support FUSE and have the appropriate libraries installed. - (See http://fuse.sourceforge.net/ for more informations).
