OpenStack Hibiscus (release 2026.2) is now available with improved security and expanded support for accelerated, high-performance infrastructure.
A key focus of Hibiscus — the latest iteration of the open source cloud software — is confidential computing, which provides organizations with “new options to protect sensitive workloads,” the company says.
Security highlights of this release include:
- The Nova component expands confidential computing support with AMD SEV-SNP and Intel TDX, providing hardware-backed memory encryption, stronger workload isolation and attestation for sensitive workloads.
- Designate strengthens DNS security with enhanced cross-tenant isolation, stronger authentication and support for TLSA/DANE, while adding new tooling to help operators prepare for post-quantum cryptography.
- Cyborg strengthens security and tenant isolation for accelerator resources, with tighter access controls and hardware management protections designed for multi-tenant environments.
“Nova and Cyborg also expand support for accelerated workloads by enabling OpenStack to manage mediated devices such as vGPUs, giving operators greater flexibility in how accelerator resources are provided and managed,” the company says.
OpenStack Hibiscus is a non-SLURP (Skip Level Upgrade Release Process) release, meaning those currently running Gazpacho can choose to skip Hibiscus and upgrade directly to the 2027.1 Indri release, which is expected in March 2027.
