In nova/cmd/manage.py, on line 294 [1] there is the following line:
if value['limit'] < 0 or value['limit'] is None:
The problem occurs when value['limit'] is None, as this line tries
to compare None (object) with an integer value.
This comparsion is totally okay (without errors) in Python27.
But, if you run this on Python34, a TypError is raised:
TypeError: unorderable types: NoneType() < int()
It is simply fixed with swapping the two expressions within the
if condition. Now if value['limit'] is None, the first expression
becomes true and second one does not get evaluated.
TrivialFix
