I must be doing something wrong here...
qemu-system-x86_64 -enable-kvm -monitor telnet:127.0.0.1:9999,server,nowait -net nic -net user,hostfwd=tcp:127.0.0.1:5555-:22 -serial file:test.qcow_serial.log -enable-kvm -m 2G,slots=4,maxmem=4G -smp 4 -numa node -numa node -object memory-backend-ram,id=mem1,size=256M -object memory-backend-ram,id=mem0,size=256M -device pc-dimm,id=dimm1,memdev=mem1,slot=1,node=0 -device pc-dimm,id=dimm0,memdev=mem0,slot=0,node=1 -drive file=test.qcow,if=ide,index=0

for i in $(seq 0 3)
do
	sh probe_memblock.sh $i
done

# ls -l /sys/devices/system/memory/memory3?/node*
lrwxrwxrwx 1 root root 0 Apr 11 11:21 /sys/devices/system/memory/memory32/node0 -> ../../node/node0
lrwxrwxrwx 1 root root 0 Apr 11 11:21 /sys/devices/system/memory/memory33/node0 -> ../../node/node0

lrwxrwxrwx 1 root root 0 Apr 11 11:21 /sys/devices/system/memory/memory35/node0 -> ../../node/node0

all of them end in the same node0
