lacp_rate=0 ('slow') is the default of the bonding module in mode=4, and we do not change that (even though we could). Please open an RFE, citing the articles that recomend the usage of faster rate. Until then - configure Engine's custom bond option to your likings. _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
