Tracing VMs - Seeing How Host and Guest Interact

Explore the intricacies of tracing virtual machines and understanding the interactions between host and guest systems in this 39-minute conference talk by Steven Rostedt from Google. Delve into the importance of tracing for quickly resolving complex issues in Linux kernel infrastructure. Learn how to leverage trace-cmd, the front-end interface to the Linux kernel ftrace infrastructure, and KernelShark to trace and visualize the connections between guest VMs and host hypervisors. Discover techniques for synchronizing events between guest and host systems to align timelines accurately. Gain valuable insights into improving performance and stability of virtual machines running on Linux hypervisors, essential knowledge for cloud deployments and encapsulated environments where VMs remain crucial despite the growing popularity of containers.
