Bug Description

Following bug 1189633, it was discovered that keystone's migrations do not explicitly define InnoDB as the desired storage engine, although that is what we recommend and test against.

In the case of RHEL, mysql's default storage engine is set to MyISAM, which causes keystone-manage db_sync to fail as of migration 23 due to a lack of support for constraints.

    Use InnoDB for MySQL

    This change adds a migration to convert any non-InnoDB tables to

    On some systems, the default engine is MyISAM, which doesn't
    support features used by Keystone (foreign keys).

    The approach is the same as what's used in Nova. A test is added
    to ensure that all tables use InnoDB after migration. The test
    passes when all the tables are mysql_engine='InnoDB'. This is
    accomplished by adding a new migration that migrates all the
    tables that aren't InnoDB to InnoDB.

    Fixes bug 1191110.
