🚀 Quick Start

Choose your deployment scenario:

📋 Common Steps (All Deployments)

Step 1: Setup OpenStack Resources

pip install octavia-loxilb-driver
# Run automated setup to create networks, flavors, and security groups
octavia-loxilb-setup

Step 2: Download and Upload LoxiLB VM Image

# Download LoxiLB VM image from releases
wget https://github.com/NLX-SeokHwanKong/octavia-loxilb-driver/releases/download/vm-v1.0.0/loxilb-vm-standard-v1.0.0.qcow2.gz

# Extract and upload to OpenStack with loxilb tag and performance properties
gunzip loxilb-vm-standard-v1.0.0.qcow2.gz
openstack image create --disk-format qcow2 --container-format bare \
    --public --tag loxilb \
    --property hw_vif_multiqueue_enabled=True \
    --property hw_vif_model=virtio \
    --property hw_disk_bus=virtio \
    --property hw_video_model=virtio \
    --property os_distro=ubuntu \
    --property os_type=linux \
    --file loxilb-vm-standard-v1.0.0.qcow2 loxilb-vm-standard

# Note: hw_vif_multiqueue_enabled=True is critical for LoxiLB performance
# It enables multiple queue networking for high-throughput packet processing

🖥️ Traditional OpenStack (systemd services)

Step 3: Install Driver on Controller Node

# Install on the controller node where Octavia services run
pip install octavia-loxilb-driver

Step 4: Configure Octavia

# Edit /etc/octavia/octavia.conf and add the generated configuration
sudo vim /etc/octavia/octavia.conf

Step 5: Restart Services

sudo systemctl restart octavia-api octavia-worker octavia-controller

🐳 Containerized Deployments

For Kolla-Ansible:

# Step 3: Install in Octavia containers
sudo docker exec octavia_api pip install octavia-loxilb-driver
sudo docker exec octavia_worker pip install octavia-loxilb-driver
sudo docker exec octavia_controller pip install octavia-loxilb-driver

# Step 4: Update kolla configuration
# Add to /etc/kolla/octavia-api/octavia.conf
# Add to /etc/kolla/octavia-worker/octavia.conf  
# Add to /etc/kolla/octavia-controller/octavia.conf

# Step 5: Restart containers
sudo docker restart octavia_api octavia_worker octavia_controller

For OpenStack-Helm (Kubernetes):

# Step 3: Update helm values to include the driver
# Add to values.yaml:
# conf:
#   octavia:
#     api_settings:
#       enabled_provider_drivers: amphora:amphora,loxilb:loxilb

# Step 4: Upgrade helm release
helm upgrade octavia ./octavia --values=values.yaml

For TripleO:

# Step 3: Add to container customization
# Create custom container image with the driver pre-installed
# Or use ExtraConfig to install during deployment

🔧 DevStack Environment

Step 3: Install in DevStack

# Install in devstack environment
source ~/devstack/openrc admin admin
pip install octavia-loxilb-driver

# Configure in local.conf for persistent setup
echo "pip install octavia-loxilb-driver" >> ~/devstack/local.sh

✅ Verification (All Deployments)

# Verify provider is available
openstack loadbalancer provider list

# Create your first LoxiLB load balancer
openstack loadbalancer create --provider loxilb --subnet-id <SUBNET_ID> my-lb

Note: For containerized deployments, you may need to rebuild container images or use persistent volume mounts to ensure the driver survives container restarts.

📋 Prerequisites

• OpenStack: Zed or later with Octavia service
• Python: 3.8+ with pip
• Access: OpenStack admin credentials and sudo access
• Resources: Available compute and network quotas
• LoxiLB VM Image: Downloaded from GitHub releases
• Manual Configuration: Octavia configuration file editing required

🏗️ Architecture

The LoxiLB Octavia Driver is a Software Load Balancer (SLB) that dynamically provisions LoxiLB VMs for each load balancer:

┌─────────────────┐    ┌──────────────────┐    ┌─────────────────┐
│   Octavia API   │───▶│  LoxiLB Driver   │───▶│ Dynamic LoxiLB VMs 
│ (Per Load Balancer)  │                  |    |                 |
└─────────────────┘    └──────────────────┘    └─────────────────┘
                               │
                               ▼
                    ┌──────────────────┐
                    │  OpenStack VMs   │
                    │ (LoxiLB Instance)│
                    └──────────────────┘

Key Components:

• Provider Driver: Main integration with Octavia API
• LoxiLB API Client: High-performance API communication with retry logic
• Resource Mapping: ID translation between Octavia and LoxiLB
• Health Monitoring: Coordinated health checking
• State Reconciliation: Ensures data consistency

⚡ Deployment Profiles

Choose the right profile for your environment:

Profile	Use Case	Resources	Command
DevStack	Development & Testing	1 vCPU, 4GB RAM	octavia-loxilb-setup --deployment-type devstack
Standard	Standard Production	2 vCPU, 8GB RAM	octavia-loxilb-setup (default)
Production	High Performance	4 vCPU, 16GB RAM	octavia-loxilb-setup --deployment-type production

🔧 Custom Configuration

For advanced deployments, create a JSON configuration file:

{
  "flavor": {
    "name": "custom-loxilb-flavor",
    "vcpus": 2,
    "ram": 4096,
