Currently, guestperf does not cover the dirty-limit
migration, support this feature.
Note that dirty-limit requires 'dirty-ring-size' set.
To enable dirty-limit, setting x-vcpu-dirty-limit-period
as 500ms and x-vcpu-dirty-limit as 10MB/s:
$ ./tests/migration/guestperf.py \
--dirty-ring-size 4096 \
--dirty-limit --x-vcpu-dirty-limit-period 500 \
--vcpu-dirty-limit 10 --output output.json \
To run the entire standardized set of dirty-limit-enabled
comparisons, with unix migration:
$ ./tests/migration/guestperf-batch.py \
--dirty-ring-size 4096 \
--dst-host localhost --transport unix \
--filter compr-dirty-limit* --output outputdir
