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

The current build structure for migration tests is confusing. There is
the tests/migration directory, which contains two different guest code
implementations, one for the qtests (a-b-{bootblock|kernel}.S) and
another for the guestperf script (stress.c). One uses a Makefile,
while the other uses meson.
The next patches will add a new qtests/migration/ directory to hold
qtest code which will make the situation even more confusing.
Move the guest code used by qtests into a new qtests/migration/
directory and rename the old one to tests/migration-stress.
