Dirty ring size configuration is not supported by guestperf tool. Introduce dirty-ring-size (ranges in [1024, 65536]) option so developers can play with dirty-ring and dirty-limit feature easier. To set dirty ring size with 4096 during migration test: $ ./tests/migration/guestperf.py --dirty-ring-size 4096 xxx Signed-off-by: Hyman Huang <yong.huang@smartx.com> Reviewed-by: Fabiano Rosas <farosas@suse.de> Signed-off-by: Juan Quintela <quintela@redhat.com> Message-ID: <8a388cec5c1f73a34d42515bbc43837e97ee3839.1698847223.git.yong.huang@smartx.com>
