Comment 11 for bug 1241275

Guys, is there any known workaround for this for Havana? Dashboard works fine for me but I get this error when I try to start an instance (using Neutron + monolithic Openvswitch plugin).

Does nova cache the old tokens somewhere somewhere on the disk? I ask, as restarting all the OpenStack services on each node and even manually deleting all the tokens from the Keystone's database does not seem the resolve the issue for me. Once I start seeing the issue the only solution seems to be reinitializing the whole OpenStack deployment on a clean drive. Reinitializing only the OpenStack DBs does not seem to do the trick, I actually have to reinstall the whole system from scratch. But then, after reinstalling, after some time I start seeing the issue again, and again...
