Currently we have no code in place for guest single stepping, but since we're looking into making use of Intel's VMFUNC and #VE, I'm sure a need for a feature like this will arrise. Or _maybe_ we can make it part of the #PF handling code and have the introspection tool respond with ALLOW and an EPT view ID and have KVM automatically switch, single step, switch back and resume, if that makes sense for everybody.
