 Hi,

 I'm using up-to-date nova.
nova-api cannot start because of the following error.
It says "AttributeError: 'module' object has no attribute 'DEFINE_string'".
I know DEFINE_string becomes obsolete and nova does not have it at all.
I checked out the keystone package from github.
It still uses "DEFINE_string".
Is it a bug?
Or is my configuration of nova is wrong?

 I'll appreciate comments/answers/...

 David.
