    Handle unicode characters in migration params
    
    There can be unicode characters in the params for live migration, for
    example, the guest domain name in the destination XML. We need to
    convert those to bytes when we call migrateToURI3 under python2.
    
    The existing code was just calling str() for this, but that will fail
    with the error:
    
      UnicodeEncodeError: 'ascii' codec can't encode characters...
    
    We need to encode the unicode characters to do conversion.
    
    The existing unit test wasn't using any unicode characters in its test
    data, so this scenario wasn't covered.

Bug description:
  when i do live migration,it raise the error as below:

  I have two computer node: compute1 ,compute2.

  The instance created at compute2 migrate to compute1 and migrate back to compute2 is work well.
  But the instance created at compute1  migrate to compute2 will make a fault as above.

  The two node configure file is same as well.
