I had to update manually table bellow for root & nova passwords at FQDN host :-

[root at dfw01 ~(keystone_admin)]$ mysql -u root -p

15  rows in set (0.00 sec)

Otherwise , nothing is going to work , just "allinone" testing. When it's done ,  your schema goes ahead on F20 Two Node Real Cluster.  I am going  to file a bug regarding this updates , because I believe it should be done behind the scene. Updated and inserted rows are responsible for remote connection to controller for nova-compute and neutron-openswitch-agent services.

Thanks
Boris.
