Building an Open Source Private 5G Network: A Practical Blueprint


Deploying a Private 5G network has traditionally been the domain of proprietary vendors with complex, closed hardware. However, the maturity of open-source projects now allows engineers to build fully functional networks using standard servers and open software. Using purely open-source components requires precise orchestration of the hardware and software stack. This session aims to demonstrate a complete, end-to-end O-RAN deployment blueprint on top of OpenNebula. We will explain how to orchestrate the srsRAN suite (providing the centralized and distributed units) and Open5GS (the 5G Core). We will dive into the specific infrastructure requirements for running latency-sensitive telco workloads, focusing on Enhanced Platform Awareness (EPA) features. Attendees will learn how to configure SR-IOV and Passthrough for optimized network throughput, implement CPU Pinning and NUMA awareness for performance isolation, and manage Precision Time Protocol (PTP) synchronization from the host to the guest VM. The session will include a walkthrough of the automation blueprints used to configure 5G-ready edge nodes and instantiate verified telco appliances from the OpenNebula Marketplace.
