Tracing with trace-cmd and ftrace has become rather standard for seeing what is happening on the running kernel. But what about events happening on the guest and how the guest interacts with the host? There is now active development to have an efficient way to trace the guest kernel activity with the events of the host and even with other guests. Coming soon to trace-cmd is the command virt-server, that will allow for the guests to be recorded and their events interleaved with the host events as well as with other guests in order to get a better view of the interactions of the entire system. This code is still under active development and has yet to be released, but this is your chance to get an inside look of what is happening with the latest developments of tracing the Linux kernel!
