Comment 1 Adriano Petrich 2019-05-16 13:56:14 UTC

There are two aspects to this error. One is that nova doesn't have the property/methods "cert" anymore. they were removed in pike 18 months ago

https://github.com/openstack/python-novaclient/commit/4bc4078fcb4f2a47269882cc83e1d637db1f37c2 I will remove them from mistral also

the other aspect is that we are not using the other and the error on registering clients that we don't use generate a bit of mess on the logs but they are innocuous and can be ignored.

I'm submitting a patch for the nova errors.
