Setting-up the COmmandline version of Cloud Mesh

Use virtualenv
----------------------

IF you have not yet done so, please install and use virtualenv. 

Checkout Cloud Mesh::

   git clone git://github.com/futuregrid/cm.git

Activate virtualenv::

   . ~/ENV/bin/activate

Install nova-client if not available::

   sudo easy_install pip
   pip install python-novaclient

For more information see

* http://docs.openstack.org/cli/quick-start/content/install_openstack_nova_cli.html

Install novaclient::

    pip install nova

Run make::

    (ENV) make

Set the key for Open Stack (You could get this key from your futuregrid account.)::

    scp gregor@india.futuregrid.org:.futuregrid/openstack/novarc .  
    cat novarc  
    mkdir -p ~/.futuregrid/openstack/  
    cp novarc ~/.futuregrid/openstack/  
    source ~/.futuregrid/openstack/novarc 

Type in a nova command to check whether the key was set properly::

    $ nova list

You will see

    +--------------------------------------+--------------+--------+------------------------------------+
    | ID                                   | Name         | Status | Networks                           |
    +--------------------------------------+--------------+--------+------------------------------------+
    | 26a41ff1-72bc-4185-a212-9d6ceXXXXXXX | Server 47XX  | ACTIVE | vlanXXX=1X.X.2.3, XXX.XXX.XXX.8    |
    +--------------------------------------+--------------+--------+------------------------------------+


If you are getting some table like above then you are good.

Install euca2ools (if you have not already done so.) ::

    $ sudo apt-get install euca2ools

Generate euca key pair (this is done wrong we want nova's commands to do that)::

    $ euca-import-keypair -f ~/.ssh/id_dsa.pub gregor

List the generated key pair::

    $ nova keypair-list

You will see

    +--------+-------------------------------------------------+
    | Name   | Fingerprint                                     |
    +--------+-------------------------------------------------+
    | gregor | shfjpaiuFEHFHEBXPNWUIXEFYBEFYPARUFIYPNERUYFPUEF |
    +--------+-------------------------------------------------+


If you are getting something like above, then you are good (I have replaced my fingerprint with 'X's)
