mdbooth / PWL Cache unwindpmp profiling.md
Last active July 4, 2023 15:36
PWL cache unwindpmp profiling
  • VM configured with rbd_cache = false in both cases
  • PWL enabled/disabled by setting rbd_plugins to pwl_cache/"" respectively
  • PWL enabled/disabled status configured by output of rbd status libvirt-pool/pwl-test
  1. Boot VM
  2. Run perf test[^1] in the guest without profiling in the host
  3. Repeat twice:
    1. Run perf test in the guest
    2. Simultaneously run unwindpmp -n 900 -p <qemu pid> > ... on the host
  4. Ensure sampling starts after and finishes before test
