Caution

Quark is not currently designed to work with DevStack (but it can with the instructions below). We mention this because these instructions can become invalid if and when changes are pushed to DevStack. Please also not that once Quark+Neutron+DevStack+Tempest are wired up, the Tempest tests are failing. Please watch this Quark Github Issue for updates on this.

Install with DevStack and Neutron

Ensure you have a user already with sudo rights. If you need one, do this as root:
```
/usr/sbin/adduser stack
echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
```

Switch to user with sudo rights:

sudo su - stack  # or whatever user you already have (instead of stack)

Clone devstack:

git clone https://github.com/openstack-dev/devstack

Go into devstack folder:
```
cd devstack
```

Create the local.conf configuration file that DevStack needs (localrc is inside it now) with Neutron as an anabled service (NOTE: This notation is explained here):

[[local|localrc]]
DATABASE_PASSWORD=password
ADMIN_PASSWORD=password
SERVICE_PASSWORD=password
SERVICE_TOKEN=password
RABBIT_PASSWORD=password
# Enable Logging
LOGFILE=/opt/stack/logs/stack.sh.log
VERBOSE=True
LOG_COLOR=True
SCREEN_LOGDIR=/opt/stack/logs

# Horizon (always use the trunk)

# Cinder
ENABLED_SERVICES+=,cinder,c-api,c-vol,c-sch
# Tempest
ENABLED_SERVICES+=,tempest

Remove Python's six packge:

# Old version of six package in /usr/lib/python2.7/dist-packages/ crashes
# quark server
sudo rm -f /usr/lib/python2.7/dist-packages/six.py /usr/lib/python2.7/dist-packages/six.pyc

Install Devstack:
```
./stack.sh
```

Install aiclib:

sudo pip install aiclib
# the reason for sudo here is if you don't you'll get permission denied when it tries to install to /usr/local/lib/python2.7/dist/packages

Install quark:

cd /opt/stack  #the folder where devstack installed all the services
git clone https://github.com/rackerlabs/quark
cd quark
sudo python setup.py develop
# the reason for sudo here is if you don't you'll get permission denied when it tries to install to /usr/local/lib/python2.7/dist/packages

Validate quark installed:

pip freeze | grep quark
# should see something like:
# -e git+http://github.com/rackerlabs/quark@ff5b05943b44a44712b9fc352065a414bb2a6bf9#egg=quark-master

Now edit the /etc/neutron/neutron.conf file to setup Quark as the core plugin:

vim /etc/neutron/neutron.conf
# Search for line containing 'core_plugin = ' and replace it with
# 'core_plugin = quark.plugin.Plugin'
#
# Search for line containing 'service_plugins = ' and remove
# 'neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,' from
# service plugins list

Stop Neutron by going into the screen session and going to the q-svc window and pressing ctrl-C:

screen -r  # or go into devstack clone and then type ./rejoin-stack.sh
# press ctrl+6 to go to q-svc window
ctrl+C

Go back into screen and restart neutron (q-svc window):

screen -r  stack # or go into folder where you cloned devstack then type ./rejoin-stack.sh
# if screen command returns 'Cannot open your terminal /dev/pts/0' execute 'sudo chmod o+rwx /dev/pts/0'
# go to q-svc window (ctrl+a, 7 currently does it)
# previous command that devstack used to start neutron should be in history, press up arrow key to see it

You shouldn't receive any errors. To validate Quark has started up, you can scroll up in q-svc screen window (ctrl+a, esc, page-up) and look for the following lines:

DEBUG neutron.service [-] core_plugin = quark.plugin.Plugin
...
DEBUG neutron.service [-] QUARK.default_ipam_strategy=ANY
DEBUG neutron.service [-] QUARK.default_net_strategy={}
DEBUG neutron.service [-] QUARK.default_network_type=BASE
DEBUG neutron.service [-] QUARK.ipam_driver=quark.ipam.QuarkIpam
DEBUG neutron.service [-] QUARK.ipam_reuse_after=7200
DEBUG neutron.service [-] QUARK.net_driver=quark.drivers.base.BaseDriver
