Attempting to install keystone in a VMWare vSphere 6 VM running CentOS 7.1 with MariaDB. When I run the "keystone_manage db_sync keystone" command, no tables / data are created in the keystone database. The keystone.log file contains the following:

[root@XLHou008018 keystone]# keystone-manage db_sync keystone
[root@XLHou008018 keystone]# cat keystone.log
