You may have resolved this by now, or given up, but a few comments (in
addition to the sqlalchemy version issues others have addressed).

The type_drivers and mechanism_drivers lists are entry point names
rather than class names, so the above line should be:

mechanism_drivers = openvswitch

> network_vlan_ranges = physnet1:1000:2999

You don't need to set the above unless you've enabled the vlan type
driver, but it won't hurt anything. If used, it needs to be in the
[ml2_type_vlan] section.

The two lines above need to be in the [ml2_type_vxlan] section.
