This session will demonstrate a scalable approach to testing Linux packages across multiple distributions and architectures using Molecule and QEMU/KVM.

Attendees will learn how to build automated testing pipelines that validate linux packages on diverse platforms including x86_64, ARM64, RHEL, Ubuntu, and Debian.

We'll cover practical implementation of Molecule test scenarios, integration with Jenkins CI/CD pipelines, efficient use of QEMU/KVM for multi-architecture testing, and image pre-baking strategies to significantly reduce test execution time.

The talk includes real-world examples from database and toolkit package testing at Percona, demonstration of creating optimized base images, comparisons with cloud instances, Docker and Firecracker alternatives, and best practices for maintaining test infrastructure.

Key takeaways: Setting up Molecule package testing frameworks, managing QEMU instances, implementing image pre-baking workflows, handling cross-architecture testing challenges, and achieving speed and cost savings in testing linux packages.
