I didn't have anything in mind, but my gut reaction is to add a new file dedicated
to tracing/tracepoints in KVM, e.g.

Documentation/virt/kvm/tracepoints.rst or Documentation/virt/kvm/tracing.rst

I'm sure there are all sorts of tips and tricks people have for using KVM's
tracepoints, it would be nice to provide a way to capture and disseminate them.
My only hesitation is that Documentation/virt/kvm/ might be too formal for what
would effectively be a wiki of sorts.
