If you are enabling `swift3` in `ENABLED_SERVICES` devstack will install the swift3 middleware emulation. Swift will be configured to act as a S3 endpoint for Keystone so effectively replacing the `nova-objectstore`.
Only Swift proxy server is launched in the screen session all other services are started in background and managed by `swift-init` tool.
# Quantum
Basic Setup
In order to enable Quantum a single node setup, you'll need the following settings in your `localrc` :
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service quantum
# Optional, to enable tempest configuration as part of devstack
enable_service tempest
Then run stack.sh as normal.
If tempest has been successfully configured, a basic set of smoke tests can be run as follows:
$ cd /opt/stack/tempest
$ nosetests tempest/tests/network/test_network_basic_ops.py
Multi-Node Setup
A more interesting setup involves running multiple compute nodes, with Quantum networks connecting VMs on different compute nodes.
You should run at least one "controller node", which should have a `stackrc` that includes at least:
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service quantum
You likely want to change your `localrc` to run a scheduler that will balance VMs across hosts:
SCHEDULER=nova.scheduler.simple.SimpleScheduler
You can then run many compute nodes, each of which should have a `stackrc` which includes the following, with the IP address of the above controller node:
ENABLED_SERVICES=n-cpu,rabbit,g-api,quantum,q-agt
SERVICE_HOST=[IP of controller node]
MYSQL_HOST=$SERVICE_HOST
RABBIT_HOST=$SERVICE_HOST
Q_HOST=$SERVICE_HOST
