[Qemu-devel] [RFC] host and guest kernel trace merging
Very recently, trace-cmd got a few new features that allow you to merge the host and guest kernel traces using the host TSC. Those features originated in the tracing we're doing to debug spikes in real-time KVM. However, as real-time KVM uses a very specific setup and as we have so far debugged a very simple application, I'm wondering: is this feature useful for the general, non-realtime, use-case
