Guest space profiling is easy, and 'perf kvm' is not about that. (plain 'perf'
will work if a proper paravirt channel is opened to the host)
I think you might have misunderstood the purpose and role of the 'perf kvm'
patch here? 'perf kvm' is aimed at KVM developers: it is them who improve KVM
code, not guest kernel users.
