Comment 3 for bug 1793976

Excellent, thank you. FYI, the actual application I'm using which requires nbd is snf-image-creator.

I agree it makes sense to remove most modules relating to physical hardware from the kvm kernel, but loopback and networking modules are useful.

I did a quick diff. "rbd" might be another one to add; also veth and vxlan.

(Aside: I was surprised to find many virtio modules missing, but since they still work, I imagine they have been compiled directly in)
