During January 2025, Beñat Gartzia enabled TDX_CAPABLE support for confidential computing workloads on Google Cloud Platform by contributing to both the coreos-assembler and osbuild-composer repositories. He implemented updates in Go to recognize TDX_CAPABLE as a valid confidential type, adjusted machine-type selection logic, and ensured the TDX_CAPABLE shield was applied during image creation. His work included cross-repository configuration changes and the addition of guest OS feature support for RHEL and CentOS images, allowing newer operating systems to run as TDX guests. This engineering effort deepened GCP’s confidential computing capabilities and streamlined provisioning for TDX-enabled cloud instances.
