reproduce = """Steps to Reproduce:

1. Install Fedora 34

2. Install virtualization group:
 
      dnf group install virtualization

4. Place SLIC binary image(slic.bin) into the direcrory /var/lib/libvirt/images

3. Create Virtual Machine with Virtual Machine Manager.

4. Modify xml description of virtual machine:
   `...
   <os>
      ...
      <acpi>
         <table type='slic'>/var/lib/libvirt/images/slic.bin</table>
      </acpi>
   </os>
   ...`

5. Install Microsoft Windows 7 64-bit into Virtual machine.

6. Place sertificate into Windows 7.

7. Run with admin rights:

       slmgr.vbs /ilc <sertificate>
       slmgr.vbs /ipk <key>

8. Windows 7 will be activated !

9. Save Virtual Machine Image and it's xml description anywere.

10. Install Fedora 35

11. Install virtualization group.

12. Place saved Virtual Machine Image and slic.bin into the directory /var/lib/libvirt/images/

13. Register virtual machine:

        virsh -c qemu:///system define <xml_file>

15. Run virtual machine - Windows 7 will lose it activation."""
