====== How to extend a disk with the CLI ======
Login to your host and do the following:
  - List the qcow2 files from your VM <code>virsh domblklist myVM</code>
  - Check the current size from the file <code>qemu-img info /var/lib/libvirt/images/myVM.qcow2</code>
  - Resize the the disk file <code>qemu-img resize /var/lib/libvirt/images/myVM.qcow2 +16G</code>
It is not required to check the current disk size, but it is good to know. You can take a look afterwards if the resize worked.
