Confidential computing will continue to evolve over the next several years. The industry still has work to do around live migration, trusted I/O, accelerator enablement, attestation, orchestration, and operational tooling. These features will not become real for users the moment they appear in a processor specification. They become real when the full software stack supports them.

Confidential computing will continue to evolve over the next several years. The industry still has work to do around live migration, trusted I/O, accelerator enablement, attestation, orchestration, and operational tooling. These features will not become real for users the moment they appear in a processor specification. They become real when the full software stack supports them. The virtualization HWE model gives Ubuntu a structured way to bring new virtualization capabilities into the LTS lifecycle, without forcing users onto interim releases.
It also gives Canonical a way to support the pace of confidential computing development while preserving the qualities that make Ubuntu LTS useful in production. With Ubuntu 26. 04 LTS and the new virtualization HWE stack, Ubuntu is better positioned to remain a leading platform for confidential computing as the technology continues to mature.
