OpenStack Compute (nova)

nova failing to install (nova.rc template missing)

Asked by dirakx

I've tested nova installation with relative success, bu i cannot create a project.

when i issue this

sudo nova-manage project zipfile myproject ttx

nova complains about a missing template and throws an error

sudo nova-manage project zipfile ORFEO rafael

I did something like the following

bzr clone lp:nova

./nova.sh branch
./nova.sh install
./nova.sh run

also i've checked and installed latest packages for ubuntu like this

$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:nova-core/trunk
$ sudo apt-get update

$ sudo apt-get install rabbitmq-server nova-api nova-objectstore
  nova-compute nova-scheduler nova-network euca2ools unzip

then while trying to do a project i got the aforementioned error.

after doing something like

$sudo nova-manage user admin user
$sudo nova-manage project create myproject user
$ sudo nova-manage project zipfile myproject user

You appear to have an old release of nova which is interfering with the system.
I suggest you remove /usr/local/lib/python2.6/dist-packages/nova-2011.1-py2.6.egg
then you should run nova-mangage from the bin dir in the nova folder that was created by nova.sh

I rm the

/usr/local/lib/python2.6/dist-packages/nova-2011.1-py2.6.egg

and it seems to work now, besides from the openssl config error.

but this is documented

''If you see an "error loading the config file './openssl.cnf'" it means you can copy the openssl.cnf file to the location where Nova expects it and reboot, then try the command again.

cp /etc/ssl/openssl.cnf ~
sudo reboot''

a las where should i put this cnf file in order to nova find it ?

Thanks soren and Vish for your kind replies
