The original concept here is that if the nodeid is omitted, it will be
set node by node from node0. Here I also keep the original concept, so the
memory will be in node0 and node1.

If no memory size is given for any nodes, the memory will split across
all nodes like (ram_size / nb_numa_nodes). And yes nodeid and cpus options
can also be omitted from the original concept.

The "-m" options will be used to compute the memory size of each node
if the memory size of each node is not set by "-numa mem" option. This
is also be consistent with the original concept.
