Guestperf tool does not cover the multifd compression option
currently, it is worth supporting so that developers can
analysis the migration performance with different
compression algorithms.
Multifd support 4 compression algorithms currently:
zlib, zstd, qpl, uadk
To request that multifd with the specified compression
algorithm such as zlib:
$ ./tests/migration-stress/guestperf.py \
--multifd --multifd-channels 4 --multifd-compression zlib \
--output output.json
To run the entire standardized set of multifd compression
comparisons, with unix migration:
$ ./tests/migration-stress/guestperf-batch.py \
--dst-host localhost --transport unix \
--filter compr-multifd-compression* --output outputdir
