How To Fix xva-img: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu xva-img is provided by xva-img package.

xva-img is:

xva-image is a tool to generate disk images from Citrix XenServer .xva VM images as well as to generate .xva VM images from raw disks and the according ova.xml files.

It’s for example needed if you want to forensically analyse a virtual machine in .xva format on a non-Citrix operating system.

Citrix Xen uses a custom virtual appliance format for import/export called “XVA”. it’s basically a strangely crafted tar-file. You don’t need this program to unpack this tar-file, just use your favourite tar unpacker (tar, gtar, bsdtar). Once unpacked you will end up with a lot of different files, ova.xml (which contains the settings for the virtual appliance, think VMware vmx) and a number of folders called Ref:/, this is your disks. Each of these folders contain hundreds of files named 00000000, 00000001 with a accompanying .CHECKSUM file (SHA1). Each file is a 1MB slice of the disk, but some of the files in the sequence will probably be missing this is because XVA do not use compression; instead it will exclude slices of the disk that only contains zeros (are empty). This tool can assemble the disk for you (you will end up with a RAW disk) that can easily be mounted and modified. It can then also split the file again and generate checksum. Once ready, you will probably want to use the “package” command to rebuild the XVA file.

To fix this problem, we can install more using the command below.

sudo apt-get -y install xva-img

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install xva-img.

sudo apt -y install xva-img

Or if you have aptitude installed you can use the following command.

sudo aptitude install xva-img
