Description
Running a workload on VM results in very disparate CPUfreq/sched behavior compared to running the same workload on the host. This difference in CPUfreq/sched behavior can cause significant power/performance regression (on top of virtualization overhead) for a workload when it is run on a VM instead of the host.
This talk will highlight some of the CPUfreq and scheduler load tracking issues/questions both at the guest thread level and at the host vCPU thread level and explore potential solutions.
