The main reason for not using the whole migration time is that it can lead to values that are not very helpful in situation where the network load changes too much.

How would that work for you? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
