If that shortcut is enabling options that fail to build, it may not be 
considered so useful.

It's contrived to not have CONFIG_NET_CORE enabled?

And why are you enabling CONFIG_PCI_MSI for systems that don't have 
ARCH_SUPPORTS_MSI?  You need CONFIG_X86_LOCAL_APIC and CONFIG_X86_IO_APIC.

So let's take a step back from your step back: you want to have a shortcut 
to build a guest.  Great, so you're enabling options that such a kernel 
needs.  The problem is that you're neglecting options that those options 
need.  It means your patch is incomplete.
