nova-manage db sync failed

try "nova-manage --flagfile=/etc/nova/nova.conf db sync"

I am very sorry.

The result is all the same.

my guess is that you have the wrong version of sqlalchemy-migrate. I would pip install the new one.

after I download the latest version of sqlalchemy-migrate(0.6.1),

an new error occurs as follows;

Thanks Vish Ishaya, that solved my question.

I received this error when I pip installed `migrate` instead of `sqlalchemy-migrate`. To fix I did:

pip uninstall migrate
pip install sqlalchemy-migrate
