Jul 1, 2025July 2025 monthly summary for microsoft/VirtualClient development. Focused on stabilizing Virtual Client in standalone runs and addressing environment permission issues to improve CI reliability. Key outcomes include implementing default ExperimentId handling by using a fixed 'default' hash seed for HammerDBExecutor and SysbenchExecutor, and updating the PostgreSQL package to resolve permission issues. These changes reduce setup friction, increase automation reliability, and enhance compatibility with enterprise environments. The work is tracked under commit c2b802030ebd958770296d138f90c1b0d3aad63d (Bug fix while working on running standalone VC without experiment ID …).
