> For the sake of our experience, we pinned vCPU0 of VM1 and vCPU0 of VM2 on the same physical CPU, and ran a CPU-intensive workload for one second one each one of them.
> We generated our traces using the low-overhead LTTng tracer. We can clearly see that during that second, both of the virtual CPUs are fighting over the same physical CPU.

   You should have said "and ran a CPU-intensive workload for one second on both of them simultaneously".  Otherwise you may be misconstrued as meaning you ran the workloads consecutively.  (The third sentence dispels this incorrect reading, but it's better to get the meaning across unambiguously the first time)
