virtme-ng v1.39 is out!

The most noticeable change in this release is the new Model Context Protocol (MCP) server. This feature lets you connect with AI assistants such as Claude, Cursor, etc., and use natural human language to automate kernel development tasks.

In this way, AI agents can automatically configure kernels, apply patches from lore.kernel.org, and run commands within recompiled kernels. You can even have the AI agent perform bug bisection for you and run specific commands/scripts inside each recompiled version to determine whether the kernel is good or bad.

An additional feature is vCPU pinning (using the --pin CPU_LIST option), which enables binding virtual CPUs to particular physical host CPUs. This ensures more consistent performance testing within the vng guest environment.

The release also adds support for memoryless NUMA nodes, enabling users to specify size=0 with the --numa argument to create NUMA nodes without memory. This capability can be useful for simulating heterogeneous architectures, where devices like GPUs are represented as memoryless NUMA nodes to model their CPU locality relationships.

Last, but not least, there's a new --shell BINARY option which lets users choose a different shell to use within the vng session, rather than using their system's default shell and a new --empty-password option that creates empty passwords in the vng guest, instead of blocking login for other users, enabling easier debugging and SSH access during testing.

Other changes:

  • Updated Python versions in CI (dropped EOL 3.8 and 3.9)
  • Various bug fixes in virtme-init
  • Enhanced documentation and README updates
  • Improved error handling and validation
