From 5fc00480ab1ce767f1c6c63ae644e960295fed2c Mon Sep 17 00:00:00 2001 From: Pavel Hrdina Date: Fri, 10 Feb 2017 10:41:17 +0100 Subject: [PATCH] monitor: add poll-* properties into query-iothreads result IOthreads were recently extended by new properties that can enable/disable and configure aio polling. This will also allow other tools that uses QEMU to probe for existence of those new properties via query-qmp-schema.
