On pseries, core-ids are strongly binded to a node-id by the command
line option. If an 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: invalid node-id, must be 0

Notes:
v4: simplify the message
v3: only add the topology to the existing message
As suggested by Igor replace
Error: core-id 30 can only be plugged into node-id 0
by
Error: node-id=1 must match numa node specified with -numa option 'node-id 0'
v2: display full topology in the error message
