I've looked at the traces but lack the skill to make any sense out of them.

Do you have specific questions about them that we could answer?

A general question: what's going on? I guess this will only be answered by me getting my hands dirty and understanding how ftrace works and how the output maps to what's happening. I'll look at the docs for a while.

A specific question for now is how can I identify long latency within qemu here? As far as I can tell all qemu latencies in trace6.txt are sub 100ms, which, while long, don't explain the guest stalling for many seconds.
