AFAICS that's not the same as the current kvmconfig functionality though: we want to minimally enable certain config options in the current .config - not pick some default config. My main usecase for this is that i want to minimally change .config's that get mailed to me, to reproduce a bug reporter's kernel as closely as possible - and be able to boot it in KVM. It's a straightforward, very useful feature, i've been using my own similar hack to do something similar for years and it works very well. Thanks, Ingo
