Easy way to use in KVM

Hello! In this quick tutorial, I will show you how to convert an OVA file to a QCOW2.

A few days ago I have to install Windows in a virtual environment to test some stuff. Then, I found that Microsoft provides some test images officially at, but there are no images to use with KVM. So, what if it would be possible to convert some provided formats to a KVM-compatible format?

Well, this is possible and much easier than I thought it was. Follow me!

First, we have to extract the files from the OVA file.


tar -xvf MSEdge-Win10.ova

An OVA file is an Open Virtualization Appliance that contains a compressed version of a virtual machine.

Now we have two files:

  • MSEdge - Win10-disk001.vmdk
  • MSEdge - Win10.ovf

To convert the .vmdk file to a .qcow2 file to import into KVM we just have to use the qemu-img command as follows.


qemu-img convert MSEdge-Win10-disk001.vmdk the_name_you_want.qcow2 -O qcow2

Observe that I’ve renamed the file MSEdge - Win10-disk001.vmdk to remove the blank spaces. I always do this before working with files in the command line, and you should too.

That’s it! Now we can just move our converted the_name_you_want.qcow2 to the images’ directory which is usually /var/lib/libvirt/images, but you can place it wherever you wish and import it.
