For a minimal guest I'd expect you wouldn't want any of the *back drivers. Did you mean for these to be the *front drivers?

I'm not the gate-keeper here so feel free to disagree but I'd like this more if it were broken up a bit. 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?
Cheers,
- Philip

This was meant more for a general case, rather than the ultra-minimalist.
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. It may be better to

I think it slipped into the dom0 config when I was testing nested in KVM.
And using that as my starting point, it slipped in again :) It should be
able to be safely removed.
Have a good one,

This image was matching up to the xen-guest kernel fragment, including the
remaining xen modules. The backend modules are not required and could be
removed from this image.
