This is a little benchmarking tool we have. You need to first build the guest workload (might need to install a couple static libraries): cd build make ./tests/migration-stress/initrd-stress.img Then: ./run ../tests/migration-stress/guestperf.py --debug --verbose --output output.json It starts a guest and migrates it, but with the --debug flag you'll already see lots of qemu.qmp debug messages flying past. Beware this is poorly maintained, I just checked it's working, but it might bite you. Let's us know!
