From 882e9b89af7c1086d97cee11b2437337e756fa00 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 7 Dec 2017 20:13:17 +0000 Subject: blockdev: add x-blockdev-set-iothread force boolean When a node is already associated with a BlockBackend the x-blockdev-set-iothread command refuses to set the IOThread. This is to prevent accidentally changing the IOThread when the nodes are in use. When the nodes are created with -drive they automatically get a BlockBackend. In that case we know nothing is using them yet and it's safe to set the IOThread. Add a force boolean to override the check.
