On pseries, core-ids are strongly binded to a node-id by the command line option. If a user tries to add a CPU to the wrong node, he has an error but it is not really helpful: qemu-system-ppc64 ... -smp 1,maxcpus=64,cores=1,threads=1,sockets=1 \ -numa node,nodeid=0 -numa node,nodeid=1 ... (qemu) device_add power9_v2.0-spapr-cpu-core,core-id=30,node-id=1 Error: node-id=1 must match numa node specified with -numa option This patch improves this error message by giving to the user the good node-id to use with the core-id he's providing: Error: core-id 30 can only be plugged into node-id 0 Signed-off-by: Laurent Vivier <lvivier@redhat.com> --- numa.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
