Speeding Up Kernel Testing and Debugging with virt-meng

Explore a powerful tool for streamlining kernel development in this conference talk from the Linux Plumbers Conference. Discover how virt-meng addresses the challenges of slow kernel testing and debugging processes. Learn about its innovative approach combining QEMU/KVM, virtio-fs, and overlayfs to create virtualized copy-on-write snapshots of running systems. Understand how this tool allows developers to "fork" their system with a new kernel, providing a safe sandbox for testing with near-native performance. Gain insights into the benefits of virt-meng for CI/CD scenarios and kernel bisecting, potentially saving significant time and resources. Additionally, explore common kernel development tools and workflows, offering valuable knowledge for both experienced developers and newcomers to the field. By attending this 44-minute talk, acquire practical techniques to enhance your kernel development process and contribute to the broader kernel community.
