Introduction

This is a hacked together test suite of a number benchmarks I use to run workloads on KVM/ARM and x86 platforms to evaluate the relative performance.

How to use

This is what you need:

  • An ARM board that can run VMs (like an A15 of some sort)
  • The ARM board must be running a KVM-enabled kernel
  • The ARM board must be accessible by ssh using public key authentication to root@<board-ip> without providing a password
  • The ARM board must have a script in root's home folder named run-ubuntu.sh, which runs a VM using either QEMU or kvmtool. Sample script for run-guest.sh is provided here - run-ubuntu.sh is just a wrapper that sets the name to ubuntu. The script will assume a file named ubuntu.img containing a file system image.
  • The guest must use bridged networking and must also accept ssh connections using public key authentication just like the board itself: ssh root@<guest-ip>

Then, to run a test, you simply do: ./run-all.sh --help ...and follow the instructions

Experiments Logbook

To carry out the full test suite, we need:

  • SMP numbers host/guest
  • UP number host/guest
  • ARM no vgic/timers guest SMP/UP
  • LMBENCH ARM/x86
  • Power Numbers

Laptop Notes

  1. Boot host with "maxcpus=2 mem=1536M" on the kernel command line
  2. Get non-graphics tty (ctrl+alt+f6)
  3. shutdown not-needed services
    1. service lightdm stop
    2. service network-manager stop
    3. service avahi-daemon stop
  4. for i in seq 0 1; do cpufreq-set -c $i -g performance; done;'
  5. ./run-all.sh --host-only
  6. TODO: LMBENCH
  7. Boot host with "maxcpus=2 mem=2048M" on the kernel command line
  8. Get non-graphics tty (ctrl+alt+f6)
  9. shutdown not-needed services
    1. service lightdm stop
    2. service network-manager stop
    3. service avahi-daemon stop
  10. sudo bash -c 'for i in seq 0 1; do cpufreq-set -c $i -g performance; done;'
  11. ./run-all.sh --guest-only
