commit 676b16bfe5ff41eb28d782c888c17dae6bdff76a
Author: Michael Still <email address hidden>
Date: Fri Apr 5 08:57:35 2013 +1100

    Fix error message in pre_live_migration.

    We are using locals() to reference a variable which doesn't exist
    in this error message. Also rename the instance variable while I
    am here to be more consistent with other uses.

    Resolves bug 1164072.
