    [libvirt] Incorrect parameters passed to migrateToURI3
    
    migrateToURI3 does not take 'bandwidth' argument so we shouldn't try
    to pass it. Actually it results with exception when libvirt>=1.2.17
    is used.
    
    Note the bandwidth parameter is already in the params list via the call
    from the libvirt driver in Nova so we don't have to check to see if it's
    already in 'params'. However, this is ugly and leaks libvirt API info
    out of the Guest object. That will be refactored and cleaned up in a
    follow-on change.
