The parameters you are passing to the query are:
('e216fcb54dc944a8ab16e4e325299643', ['Server Group'], ['DOM1'])
but I suspect they should be
('e216fcb54dc944a8ab16e4e325299643', 'Server Group', 'DOM1')
ie. the last 2 elements should be strings, not single-element lists.
If you are getting these from a web form, are they perhaps
multiple-selection fields? In which case you'll probably want to
change the search conditions to be something like:
models.InstanceMetadata.key.in_(search_opts['key'])
However, you should only add that condition if search_opts['key'] is
not empty. (I *think* SA warns you if you pass an empty list to "in_")
