Create vm instance failed, the reason is http 500
I have an issue when I tried to create vm instance, and the failed reason as below:
Resource CREATE failed: ClientException: resources.node:App04:server: The server has either erred or is incapable of performing the requested operation. (HTTP 500)
I'm using CentOS 7.2 and Kilo.
I also checked the /var/log/nova/nova-api.log on the controller, and get this:
2016-08-08 17:11:13.521 22093 TRACE nova.api.openstack PortNotFoundClient: Port 14c7bbf2-d1b7-4410-8c1d-76a7690c8903 could not be found
