Setting up a Virtual Machine
The images generated are compressed raw disk images. They can be utilised both on physical devices and used as disks on a virtualisation platform. The images work without change on qemu/KVM.
On qemu/KVM the tools that can be used to run the image in a VM include Virtual Machine Manager, GNOME Boxes or virsh cli. These tools are available in most Linux distributions. Decompress the image as below and then create a new virtual machine and when asked for storage point the tool at the existing disk image.
$ xz -d [filename].raw.xz
