We shouldn't duplicate kvm_guest.config.

I've not yet had defconfig+kvm_guest.config fail to boot on debian
images (I occasionally grab one here:
https://cloud.debian.org/images/cloud/sid/daily/latest/ )

I think x86-defconfig should be usable by itself - not just via the 
somewhat obscure combination of:

  make defconfig
  make kvm_guest.config

right?

Systemd is rather negative about missing cgroup features - at a point it 
used to insert 30(?) seconds delays during bootup warning about missing 
cgroups support, etc.

Also the main Debian derived distros (Ubuntu, etc.) plus Debian itself has 
most of cgroups enabled - so why should we test something that very few 
users are using?

Thanks,

	Ingo

Dunno, i've been using it forever (+- the kvmconfig rename thing, which
was really annoying).

But these days I have it scripted anyway, I also typically add
DEBUG_INFO to any .config that I end up booting.

Yeah, don't mind. I just hadn't had problems booting anything.
