-Devstack with Octavia Load Balancing
-====================================
-
-Starting with the OpenStack Pike release, Octavia is now a standalone service
-providing load balancing services for OpenStack.
-
-This guide will show you how to create a devstack with `Octavia API`_ enabled.
-
-.. _Octavia API: https://docs.openstack.org/api-ref/load-balancer/v2/index.html
-
-Phase 1: Create DevStack + 2 nova instances
---------------------------------------------
-
-First, set up a vm of your choice with at least 8 GB RAM and 16 GB disk space,
-make sure it is updated. Install git and any other developer tools you find
-useful.
-
-Install devstack
-
-::
-
-    git clone https://opendev.org/openstack/devstack
-    cd devstack/tools
-    sudo ./create-stack-user.sh
-    cd ../..
-    sudo mv devstack /opt/stack
-    sudo chown -R stack.stack /opt/stack/devstack
-
-This will clone the current devstack code locally, then setup the "stack"
-account that devstack services will run under. Finally, it will move devstack
-into its default location in /opt/stack/devstack.
-
-Edit your ``/opt/stack/devstack/local.conf`` to look like
-
-::
-
-    [[local|localrc]]
-    enable_plugin octavia https://opendev.org/openstack/octavia
-    # If you are enabling horizon, include the octavia dashboard
-    # enable_plugin octavia-dashboard https://opendev.org/openstack/octavia-dashboard.git
-    # If you are enabling barbican for TLS offload in Octavia, include it here.
-    # enable_plugin barbican https://opendev.org/openstack/barbican
-
-    # ===== BEGIN localrc =====
-    DATABASE_PASSWORD=password
-    ADMIN_PASSWORD=password
-    SERVICE_PASSWORD=password
-    SERVICE_TOKEN=password
-    RABBIT_PASSWORD=password
-    # Enable Logging
-    LOGFILE=$DEST/logs/stack.sh.log
-    VERBOSE=True
-    LOG_COLOR=True
-    # Pre-requisite
-    ENABLED_SERVICES=rabbit,mysql,key
-    # Horizon - enable for the OpenStack web GUI
-    # ENABLED_SERVICES+=,horizon
-    # Nova
-    ENABLED_SERVICES+=,n-api,n-crt,n-cpu,n-cond,n-sch,n-api-meta,n-sproxy
-    ENABLED_SERVICES+=,placement-api,placement-client
-    # Glance
-    ENABLED_SERVICES+=,g-api
-    # Neutron
-    ENABLED_SERVICES+=,q-svc,q-agt,q-dhcp,q-l3,q-meta,neutron
-    ENABLED_SERVICES+=,octavia,o-cw,o-hk,o-hm,o-api
-    # Cinder
-    ENABLED_SERVICES+=,c-api,c-vol,c-sch
-    # Tempest
-    ENABLED_SERVICES+=,tempest
-    # Barbican - Optionally used for TLS offload in Octavia
-    # ENABLED_SERVICES+=,barbican
-    # ===== END localrc =====
-
-Run stack.sh and do some sanity checks
-
-::
-
-    sudo su - stack
-    cd /opt/stack/devstack
-    ./stack.sh
-    . ./openrc
-
-    openstack network list  # should show public and private networks
-
-Create two nova instances that we can use as test http servers:
-
-::
-
-    #create nova instances on private network
-    openstack server create --image $(openstack image list | awk '/ cirros-.*-x86_64-.* / {print $2}') --flavor 1 --nic net-id=$(openstack network list | awk '/ private / {print $2}') node1
-    openstack server create --image $(openstack image list | awk '/ cirros-.*-x86_64-.* / {print $2}') --flavor 1 --nic net-id=$(openstack network list | awk '/ private / {print $2}') node2
-    openstack server list # should show the nova instances just created
-
-    #add secgroup rules to allow ssh etc..
-    openstack security group rule create default --protocol icmp
-    openstack security group rule create default --protocol tcp --dst-port 22:22
-    openstack security group rule create default --protocol tcp --dst-port 80:80
-
-Set up a simple web server on each of these instances. ssh into each instance (username 'cirros', password 'cubswin:)' or 'gocubsgo') and run
-
-::
-
-    MYIP=$(ifconfig eth0|grep 'inet addr'|awk -F: '{print $2}'| awk '{print $1}')
-    while true; do echo -e "HTTP/1.0 200 OK\r\n\r\nWelcome to $MYIP" | sudo nc -l -p 80 ; done&
-
-Phase 2: Create your load balancer
-----------------------------------
-
-Make sure you have the 'openstack loadbalancer' commands:
-
-::
-
-    pip install python-octaviaclient
-
-Create your load balancer:
-
-::
-
-    openstack loadbalancer create --name lb1 --vip-subnet-id private-subnet
-    openstack loadbalancer show lb1  # Wait for the provisioning_status to be ACTIVE.
-    openstack loadbalancer listener create --protocol HTTP --protocol-port 80 --name listener1 lb1
-    openstack loadbalancer show lb1  # Wait for the provisioning_status to be ACTIVE.
-    openstack loadbalancer pool create --lb-algorithm ROUND_ROBIN --listener listener1 --protocol HTTP --name pool1
-    openstack loadbalancer show lb1  # Wait for the provisioning_status to be ACTIVE.
-    openstack loadbalancer healthmonitor create --delay 5 --timeout 2 --max-retries 1 --type HTTP pool1
-    openstack loadbalancer show lb1  # Wait for the provisioning_status to be ACTIVE.
-    openstack loadbalancer member create --subnet-id private-subnet --address <web server 1 address> --protocol-port 80 pool1
-    openstack loadbalancer show lb1  # Wait for the provisioning_status to be ACTIVE.
-    openstack loadbalancer member create --subnet-id private-subnet --address <web server 2 address> --protocol-port 80 pool1
-
-Please note: The <web server # address> fields are the IP addresses of the nova
-servers created in Phase 1.
-Also note, using the API directly you can do all of the above commands in one
-API call.
-
-Phase 3: Test your load balancer
---------------------------------
-
-::
-
-    openstack loadbalancer show lb1 # Note the vip_address
-    curl http://<vip_address>
-    curl http://<vip_address>
-
-This should show the "Welcome to <IP>" message from each member server.

+
+.. note::
+    For best performance it is highly recommended to use KVM
+    virtualization instead of QEMU.
+    Also make sure nested virtualization is enabled as documented in
+    :ref:`the respective guide <kvm_nested_virt>`.
+    By adding ``LIBVIRT_CPU_MODE="host-passthrough"`` to your
+    ``local.conf`` you enable the guest VMs to make use of all features your
+    host's CPU provides.
+
+Run stack.sh and do some sanity checks::
+
+    sudo su - stack
+    cd /opt/stack/devstack
+    ./stack.sh
+    . ./openrc
+
+    openstack network list  # should show public and private networks
+
+Create two nova instances that we can use as test http servers::
+
+    # create nova instances on private network
+    openstack server create --image $(openstack image list | awk '/ cirros-.*-x86_64-.* / {print $2}') --flavor 1 --nic net-id=$(openstack network list | awk '/ private / {print $2}') node1
+    openstack server create --image $(openstack image list | awk '/ cirros-.*-x86_64-.* / {print $2}') --flavor 1 --nic net-id=$(openstack network list | awk '/ private / {print $2}') node2
+    openstack server list # should show the nova instances just created
+
+    # add secgroup rules to allow ssh etc..
+    openstack security group rule create default --protocol icmp
+    openstack security group rule create default --protocol tcp --dst-port 22:22
+    openstack security group rule create default --protocol tcp --dst-port 80:80
+
+Set up a simple web server on each of these instances. One possibility is to use
+the `Golang test server`_ that is used by the Octavia project for CI testing
+as well.
+Copy the binary to your instances and start it as shown below
+(username 'cirros', password 'gocubsgo')::
+
+    INST_IP=<instance IP>
+    scp -O test_server.bin cirros@${INST_IP}:
+    ssh -f cirros@${INST_IP} ./test_server.bin -id ${INST_IP}
+
+When started this way the test server will respond to HTTP requests with
+its own IP.
+
+Phase 2: Create your load balancer
+----------------------------------
+
+Create your load balancer::
+
+    openstack loadbalancer create --wait --name lb1 --vip-subnet-id private-subnet
+    openstack loadbalancer listener create --wait --protocol HTTP --protocol-port 80 --name listener1 lb1
+    openstack loadbalancer pool create --wait --lb-algorithm ROUND_ROBIN --listener listener1 --protocol HTTP --name pool1
+    openstack loadbalancer healthmonitor create --wait --delay 5 --timeout 2 --max-retries 1 --type HTTP pool1
+    openstack loadbalancer member create --wait --subnet-id private-subnet --address <web server 1 address> --protocol-port 80 pool1
+    openstack loadbalancer member create --wait --subnet-id private-subnet --address <web server 2 address> --protocol-port 80 pool1
+
+Please note: The <web server # address> fields are the IP addresses of the nova
+servers created in Phase 1.
+Also note, using the API directly you can do all of the above commands in one
+API call.
+
+Phase 3: Test your load balancer
+--------------------------------
+
+::
+
+    openstack loadbalancer show lb1 # Note the vip_address
+    curl http://<vip_address>
+    curl http://<vip_address>
+
+This should show the "Welcome to <IP>" message from each member server.
