Convert Citrix Xenserver XVA Image to KVM

Tags: , ,

qemu-img is a tool apart of the qemu-utils package that lets you convert a wide variety of disk images from one hypervisor to another. However Citrix Xenserver image format XVA is not an option for qemu-img, so lets add it!

Here’s how to convert an XVA image to KVM.

Extract the XVA image.

A XVA file is a carefully created tarball we will need to extract.

mkdir xva_uncompressed
tar -xf virtual_machine.xva -C xva_uncompressed

Create a raw image

Use xva-img to create a raw disk image from the extracted xva data.

First we will build xva-img:

git clone
cd xva-img/
cmake .
sudo make install
cd ../

Create raw disk image: Note the Ref\:1 may be different.

xva-img -p disk-export xva_uncompressed/Ref\:1/ virtual_machine.raw

Convert RAW image to KVM using qemu-img

Install qemu-utils

sudo apt-get install qemu-utils
sudo yum install qemu-kvm qemu-img

Covert raw image to qcow2

qemu-img convert -f raw -O qcow2 virtual_machine.raw virtual_machine.qcow2

Import qcow2 disk image to KVM

Import the qcow2 image to your KVM environment, then attach the image to a VM. In my environment, I use oVirt:
