Cyclades Setup

The following apply to cyclades node. In the rest of the sections we will refer to its IP with FQDN cyclades.example.com.Please make sure you have db, mq, gunicorn, apache, webproject, pithos and astakos already setup.

Install the corresponding package. Please note that memcache is needed for versions >= 0.13 :

# apt-get install memcached
# apt-get install python-memcache
# apt-get install kamaki
# apt-get install snf-pithos-backend
# apt-get install snf-cyclades-app

In /etc/synnefo/cyclades.conf add:

UI_SYSTEM_IMAGES_OWNERS = {

    'images@synnefo.gr': 'system'
}

XXXXXXXX is the token for cyclades registered service and can be found in astakos node running:

snf-manage service-list

Restart services and initialize database:

# /etc/init.d/gunicorn restart
# /etc/init.d/apache2 restart
# snf-manage syncdb
# snf-manage migrate --delete-ghost-migrations
# snf-manage loaddata flavors

Enable dispatcher:

# sed -i 's/false/true/' /etc/default/snf-dispatcher
# /etc/init.d/snf-dispatcher start

In order end-user to have access to the VM’s console:

# apt-get install snf-vncauthproxy

Edit /etc/default/vncauthproxy:

CHUID="www-data:nogroup"

At this point you should setup a backend. Please refer to the coresponding section. Here we assume that at least one backend is up and running, so we can add it in Cyclades with:

# snf-manage backend-add --clustername=ganeti.example.com --user=synnefo --pass=example_rapi_passw0rd

After 0.13 every backend added stays in drained mode (no VMs can be added). Therefore get your backend ID (propably 1) and run:

# snf-manage backend-list
# snf-manage backend-modify --drained=False 1

Further assumptions:

• Preprovisioned Bridges: br0, prv0, prv1..prv20
• Available “public” Subnet: 10.0.1.0/24
• Available “public” Gateway: 10.0.1.1
• Connectivity link for public network: br0

Here admin has to define two different resource pools in Synnefo:

• MAC prefix Pool
• Bridge Pool

# snf-manage pool-create --type=mac-prefix --base=aa:00:0 --size=65536
# snf-manage pool-create --type=bridge --base=prv --size=20

Add the Synnefo setting in /etc/synnefo/cyclades.conf:

DEFAULT_MAC_FILTERED_BRIDGE = 'prv0'

Add public network where the VM’s will eventually connect to in order to access Internet:

# snf-manage network-create --subnet=10.0.1.0/24 --gateway=10.0.1.1 --public --dhcp=True --flavor=CUSTOM --mode=bridged --link=br0 --name=Internet --backend-id=1

Test your Setup:

In cyclades node run:

snf-manage backend-list
snf-manage network-list
snf-manage server-list

Visit https://cyclades.example.com/ui/ and create a VM or network.
