so I'm currently experimenting with my randconfig build scripts and

have that KVMTOOL_TEST_ENABLE config option in the kvmtool with which we
can select all the stuff needed to boot the kernel in kvm.

So I copied it. I now have an all.config in the repo with
CONFIG_KVM_TEST_ENABLE=y in it so that the random builds can have the
required support.

So what do people think?

It is pretty helpful for such testing; AFAICT Fengguang is doing his
testing with kvm so he probably could use it too. And regardless, there
are more and more reasons to boot the kernel in kvm so having a single
option which selects the needed support makes more sense with time.

And I haven't picked up the 'make kvmconfig' functionality because it
is not strictly needed (yet) but it wouldn't hurt if we took it because
someone has a good reason for needing it.

I obviously support having something like this in mainline. I wonder though if we could just call this "default standalone KVM guest config" instead of emphasizing testing angle.
