The _create_domain() method has the following line:
err = _LE('Error defining a domain with XML: %s') % xml
which fails with the UnicodeDecodeError because the xml object has
utf-8 encoding. The fix is to wrap the xml object in
oslo.utils.encodeutils.safe_decode for the error message.
I'm seeing the issue on Kilo, but it is also likely an issue on Juno
as well.
