Hi all,

I'm doing some profiling of my hypervisor as it executes a workload.  I noticed periods of high latency and I want to figure out what's going on.

I'm running xentrace and a kernel trace as well with trace-cmd (ftrace).  I'd like to correlate the results.  For example, kernelshark is a great way to visualize kernel traces and I want to see what the kernel and hypervisor are both doing.  It would be helpful to see the xen trace events in there as well.  Is there an easy way to accomplish this?

Thanks,
Ian
