Patch is -2'ed.
It's unfortunate but looks like we will have to live with this behavior.

Title:
Instance object String field coercion of bool value is surprising
Status in OpenStack Compute (Nova):
Won't Fix
Bug description:
So in the process of converting certain test case from using an
instance dict to a fake instance object, I noticed the following:
self.instance_object.config_drive = False
self.assertFalse(self.instance_object.config_drive) # <<<< Fails
The reason the config_drive attribute is exhibiting this behavior is because
it is actually declared as a String in the schema
(see related bug: https://bugs.launchpad.net/nova/+bug/1193438), and
assignment of a bool value to it results in coercion to u'False' which
evaluates to True in the boolean context.
While this issue can easily be worked around in the config drive unit
test (or with some conversion in the configdrive module where the
attribute is used), it would be less surprising in general for a bool
False value to be coerced to a string that once again evaluates to
False.
