- [Deployment Method Selection Guide](https://kvm.xdr.ooo/getting-started/deployment-guide.md): Choose a Stellar Cyber OpenXDR deployment model based on infrastructure, performance needs, and operational constraints.
- [Requirements](https://kvm.xdr.ooo/getting-started/requirements.md): Review host, BIOS, operating system, storage, network, and access requirements before deployment.
- [Ubuntu Server 24.04 LTS Installation Guide](https://kvm.xdr.ooo/getting-started/installing-ubuntu-24-04.md): Ubuntu Server 24.04 LTS installation, BIOS, storage, profile, and network preparation for OpenXDR KVM deployment.
- [Quickstart](https://kvm.xdr.ooo/getting-started/quickstart.md): Clone the source and begin the DRY_RUN, validation, execution, and resume workflow.
- [Installation Demo Videos](https://kvm.xdr.ooo/getting-started/installation-demo-videos.md): Watch three OpenXDR KVM installation demonstration videos alongside the written deployment guides.

### Installer Guides

- [DP KVM Installer User Guide](https://kvm.xdr.ooo/installers/dp.md): Install, configure, validate, and operate the Stellar Cyber OpenXDR Data Platform on an Ubuntu Server 24.04 LTS KVM host.
- [DP Cluster Initial Configuration](https://kvm.xdr.ooo/installers/dp-cluster-initial-configuration.md): Configure DL Master, DL Workers, and DA nodes after KVM deployment using the fixed KVM NAT addressing model and dedicated cluster interfaces.
- [Sensor KVM Installer User Guide](https://kvm.xdr.ooo/installers/sensor.md): Complete procedure for installing, configuring, validating, and operating a Stellar Cyber OpenXDR Sensor VM on an Ubuntu Server 24.04 LTS KVM host.
- [AIO & Sensor KVM Installer User Guide](https://kvm.xdr.ooo/installers/aio-sensor.md): Install, deploy, validate, and maintain Stellar Cyber OpenXDR AIO and Sensor VMs on an Ubuntu Server 24.04 LTS KVM host.
- [AIO & Sensor Initial Configuration](https://kvm.xdr.ooo/installers/aio-sensor-initial-configuration.md): Configure the AIO and Sensor after KVM deployment, including fixed NAT networking, AIO initialization, storage, Sensor registration, authorization, and receiver validation.

### Operations

- [DRY_RUN & Validation](https://kvm.xdr.ooo/operations/dry-run-validation.md): Use DRY_RUN and Full Configuration Validation to inspect a deployment before making system changes.
- [Reboot & Resume](https://kvm.xdr.ooo/operations/reboot-resume.md): Understand intentional reboot points, persistent state and safe continuation.
- [Troubleshooting](https://kvm.xdr.ooo/operations/troubleshooting.md): Use logs, validation and step-level retry to diagnose installer failures without restarting the entire workflow.
- [Stellar Appliance CLI User Guide](https://kvm.xdr.ooo/operations/appliance-cli.md): Operate post-deployment networking, NTP, ACLs, virtual machines, and system settings on OpenXDR KVM hosts with Stellar Appliance CLI.

## Reference

### Architecture

- [Architecture](https://kvm.xdr.ooo/reference/architecture.md): Understand how the Ubuntu KVM host, libvirt, storage and OpenXDR VMs fit together.
- [Networking](https://kvm.xdr.ooo/reference/networking.md): Reference management, VM, SPAN, SR-IOV and passthrough networking across the active installer families.
- [Storage & Performance](https://kvm.xdr.ooo/reference/storage-performance.md): Reference LVM storage preparation, CPU placement, NUMA and direct-device assignment.

### Operator Reference

- [Installer Step Matrix](https://kvm.xdr.ooo/reference/step-matrix.md): Compare the current ordered workflow of the three installer families documented on this site.
- [State & Logs](https://kvm.xdr.ooo/reference/state-logs.md): Find installer configuration, persistent state and log files.
- [Post-deployment Operations](https://kvm.xdr.ooo/reference/post-deployment.md): Validate deployed VMs and move from installation into normal KVM host operations.
