From 2ff30257974e19ebe2a97baad32ac29c06da5fb9 Mon Sep 17 00:00:00 2001 From: Ashijeet Acharya Date: Thu, 15 Sep 2016 21:50:28 +0530 Subject: migrate: move max-bandwidth and downtime-limit to migrate_set_parameter Mark the old commands 'migrate_set_speed' and 'migrate_set_downtime' as deprecated. Move max-bandwidth and downtime-limit into migrate-set-parameters for setting maximum migration speed and expected downtime limit parameters respectively. Change downtime units to milliseconds (only for new-command) and set its upper bound limit to 2000 seconds. Update the query part in both hmp and qmp qemu control interfaces.
