We’re excited to introduce OpenNebula 7.0 “Phoenix” as the first major release in the new 7.x series, marking a significant evolution of the platform. Just like the mythological bird rising from its ashes, this release symbolizes resilience and transformation—a fitting name for a platform reinventing itself in the face of emerging trends in AI and multi-cloud. With 7.0, OpenNebula takes a giant leap forward to help organizations modernize their infrastructure, embrace next-generation workloads, and break free from legacy virtualization platforms like VMware.
A key highlight of OpenNebula 7.0 is the inclusion of migration packages in the Community Edition, making it easier for community users to stay up to date and take full advantage of the latest innovations.
Another big plus of 7.0 is the introduction of OpenNebula Distributed Resource Scheduler (OneDRS), delivering predictive scheduling, customizable policies, and automated VM migrations to ensure optimal resource utilization across your infrastructure. OneDRS analyzes historical and real-time metrics to anticipate demand spikes and proactively balance workloads—minimizing contention and maximizing performance.
OpenNebula 7.0 is designed for modern workloads, with enhancements to support:
OpenNebula 7.0 continues the effort to streamline the platform by removing or deprecating legacy and little-used components, simplifying the architecture, and ensuring the long-term maintainability of the platform. The FireEdge-based Sunstone UI is now the standard web interface, with a growing list of UI components and dashboards.
Component | Status | Replacement / Notes |
---|---|---|
Ruby Sunstone | Removed | Fully replaced by FireEdge UI |
vCenter driver | Legacy | Use KVM migration tools |
LXD & Docker drivers | Removed | OneKE & LXC |
OpenNebula 7.0 is named after the Phoenix Nebula, a spectacular cosmic structure located in the constellation of the same name. This nebula is a dynamic region of gas and dust shaped by intense stellar winds and supernova activity—an evocative symbol of transformation, power, and renewal. Like the Phoenix Nebula rising from the remnants of massive stars, OpenNebula 7.0 rises as a robust, flexible, and modern open source cloud platform ready for the AI-driven future.
OpenNebula 7.0 “Phoenix” is a stable, production-ready release, available to all users. We encourage you to:
We’d like to thank our global community and partners who have helped shape this release, and specailly to those that support the project. OpenNebula is what it is because of your support—keep being awesome!
