Could you please point, which ones?
I haven't changed any, and yet my host is running fine.

IMO current kvmconfig doesn't fulfill this purpose, because trying

- "make defconfig kvmconfig"
- "make localmodconfig kvmconfig"
- "gunzip -c /proc/config.gz > .config && make olddefconfig" (rescue
  system had way too old kernel I guess)

didn't save me a lot of hours wasted searching for all those options to
make it boot.

IMO "bare minimum" term makes sense if it boots. If it doesn't, then
"bare minimum" for what we are talking about?

Borislav, could you please tell, which options from this patch are you
using in your configs? Sorry to bother you.

Thank you for your interest.
