Many modern workloads run inside VMs making it harder to reason about the overall system performance when faced with a problem caused by VMs competing for shared host resources or issues caused by the interaction between the host and guest kernels.In this presentation Slavomir and Tzvetomir will discuss a set of recent trace-cmd features allowing for capturing of kernel traces from several running VMs or simultaneously recording of host kernel tracing data alongside the VM kernel traces. The resulting trace streams are automatically synchronized during recording and can later be loaded in KernelShark for visual analysis of the data.
