From 904e5fd5c25537fdf910bfd5db832df5d9c23ad6 Mon Sep 17 00:00:00 2001 From: Viktor Mihajlovski Date: Tue, 18 Dec 2012 07:50:59 +0000 Subject: S390: Enable -cpu help and QMP query-cpu-definitions This enables qemu -cpu help to return a list of supported CPU models on s390 and also to query for cpu definitions in the monitor. Initially only cpu model = host is returned. This needs to be reworked into a full-fledged CPU model handling later on. This change is needed to allow libvirt exploiters (like OpenStack) to specify a CPU model.
