To resolve this issue, use one of these methods:
Gets the novarc file from the project ZIP file, saves existing credentials in case of override, and manually sources the novarc file.
Generates novarc from the project ZIP file and sources it for you.
When you run nova-api the first time, it generates the certificate authority information, including openssl.cnf. If you start the CA services before this, you might not be able to create your ZIP file. Restart the services. When your CA information is available, create your ZIP file.
Also, check your HTTP proxy settings to see whether they cause problems with novarc creation.
Hope this will help.
