I moved to a different system which hadn't been configured with an earlier
version of OVS, built and installed the 2.3.90 version, modified my
interfaces file as previously described, and now the system creates the 
devices at boot and deletes them at shutdown.  I must have made some 
other change on the original system to give me a problem. 

Thanks for the help.
