[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit 8f6b5ad41e2407daab59f80206c7edfd54c9a02d
Author: Zeeshan Ali (Khattak) <zeeshanak gnome org>
Date:   Sat Nov 16 19:12:11 2013 +0000

    Restore system libvirt imports from previous runs
    
    Save the state for system libvirt imports so that if Boxes is quite
    before import is finished, the import is restarted next time Boxes is
    run.
