Hey,

I'm setting up a test lab for personal use following the official [CentOS 7 install guide] ( http://docs.openstack.org/juno/install-guide/install/yum/content/ (http://docs.openstack.org/juno/instal...) )

When I try to run an instance as the demo user (sourced demo-openrc.sh) with this command

nova --debug boot --flavor m1.medium --image cirros-0.3.3-x86_64 --nic net-id=bfc92b52-8202-4333-9aac-401407dd4184 --security-group default --key-name demo-key my-instance

an error states:

ClientException: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-b12665bb-e140-4ef7-b29f-3a0361977118

Logs aren't showing anything useful other than successful RabbitMQ connections. I'm attaching nova --debug info for further debugging because it contains one 404 error regarding flavors. http://pastebin.com/2KXpht4V
