trace-cmd is a front end user space tool to interact with ftrace, the official tracing infrastructure of the Linux Kernel. Ftrace allows one to see inside their kernel to examine what exactly is happening under the covers. With the focus on virtual machines, the interaction between host and guest needs more work on the tracing front. A new option is being developed in the trace-cmd tool suite to allow for admins to view the events that happen between host and guest. This will allow one to see events as they occur in the host and how those events affect the guest. The work is still in progress, which allows the audience of this talk to have their say in how the final product will end up.
