Required features for kernel and VMs?

[zmitchell]

Hi, looking at the build_image.sh and build_kernel.sh scripts, they both say that they're for building vmtest-ready images/kernels. Could you be more specific about what this means? For example, are there certain kernel config parameters that are required, or does the guest image need anything other than qemu-guest-agent?

I see that the images are built with Nix, and I'm wondering what's necessary for building a vmtest-ready VM or kernel with Nix using a custom config.

Hi, those scripts are used by CI to test vmtest itself. You could use those as reference to see how to build a vmtest-ready kernel image. I probably wouldn't recommend that.

See the README for what configs a kernel needs to have - it should be fairly straightforward: https://github.com/danobi/vmtest?tab=readme-ov-file#dependencies
