What's wrong?I think nova 8774 port didn't open.Because I writting "service nova-api start ; nova list",and then it works.

netstat -nlp | grep 8774

has nothing.

Had the same problem, found that in /var/log/nova/nova-api.log the error message:

Stderr: 'Traceback (most recent call last):\n File "/usr/bin/nova-rootwrap", line 6, in \n from oslo.rootwrap.cmd import main\nImportError: No module named rootwrap.cmd\n'

Solution:Reinstalled oslo with the command: pip install --upgrade oslo.rootwrap
