If you upgraded or manually installed OVS, this can be caused by libvirtd fails to find `ovs-vsctl` or refers to the stale version of the binary. Try to cleanup the existing OVS and install it again. This guide works very well for me (don't forget to change the version in the guide to 2.3.0 or later).

SONA version lower than ONOS 1.10 does not support Keystone 3.0. Refer to the following link to enable Keystone 2.0 in OpenStack.
