From ab980ce5d6792a273db3e93eb3d163bfdc38b1de Mon Sep 17 00:00:00 2001 From: Matt Riedemann Date: Tue, 1 Aug 2017 16:38:42 -0400 Subject: [PATCH] Disable track_instance_changes when in superconductor mode When configured for superconductor mode, which is the default, nova-compute can't reach the MQ for nova-scheduler so there is no point in even enabling the track_instance_changes code since it's a waste of time as the scheduler will never get the message.
