Turns out that installing M2Crypto-0.21.1.tar.gz caused the problem. .21.1 had a regression in it and by going by to the version that came with Ubuntu .20.1, nova-manage worked without problem.

I deleted this file.
/usr/local/lib/python2.7/dist-packages/M2Crypto-0.21.1-py2.7-linux-x86_64.egg

Then I did an apt-get M2Crypto and Ubuntu installed vs 20.1.
