Guestperf tool does not cover the multifd-enabled migration
currently, it is worth supporting so that developers can
analysis the migration performance with all kinds of
migration.
To request that multifd is enabled, with 4 channels:
$ ./tests/migration/guestperf.py \
--multifd --multifd-channels 4 --output output.json
To run the entire standardized set of multifd-enabled
comparisons, with unix migration:
$ ./tests/migration/guestperf-batch.py \
--dst-host localhost --transport unix \
--filter compr-multifd* --output outputdir
