Open Stack

Hello together,

In the last days a played with multi-node installation of devstack:

http://devstack.org/guides/multinode-lab.html

However I tried to use CentOS 6.2 machines for Computes Nodes and a normal
Ubuntu 12.04 for Head Node.

On the compute nodes I want to run n-cpu (nova-compute) and n-net
(nova-network). However after the stack.sh run there are still missing some
"API" modules  if I try to run nova-manage.

If I try to install n-cpu, n-net AND n-api, the stack.sh script will crash
because of the nova-api service with the following message:

CRITICAL nova [-] Could not load paste app 'ec2' from
/etc/nova/api-paste.ini
TRACE nova Traceback (most recent call last):
TRACE nova   File "/usr/bin/nova-api", line 51, in <module>
TRACE nova     servers.append(service.WSGIService(api))
TRACE nova   File "/usr/lib/python2.6/site-packages/nova/service.py", line
326, in __init__
TRACE nova     self.app = self.loader.load_app(name)
TRACE nova   File "/usr/lib/python2.6/site-packages/nova/wsgi.py", line 391,
in load_app
TRACE nova     raise exception.PasteAppNotFound(name=name,
path=self.config_path)
TRACE nova PasteAppNotFound: Could not load paste app 'ec2' from
/etc/nova/api-paste.ini


Does anybody have an idea, what is going wrong?

Cheers Viktor
