Thoughts on breaking guest support out into a PV guest and a PVHVM guest? The goal here would be to partition the kernel options that aren't modules (specifically PVHVM, DOM0, PVMMU, PRIVILEGED_GUEST etc). No need to do all of this on the first past I suppose. It may be better to have someone propose a partitioning after this gets picked up. Also: what's with having 'KVM_GUEST' compiled in? Is it a dependency?

It could certainly be broken up more. But then, it's not entirely clear to me where you draw the line. It appears to me that many yocto kernel configs/fragments tend to build in a significant amount of hardware device support instead of requiring modules. My thoughts were to make the backend bits as modules and build in the common front ends (which is effectively virtual hardware support) and basics (PVHVM, etc). On that note, I set pcifront as a module in this fragment, which should probably also be built in. No need to do all of this on the first past I suppose.
