-  numa=fake=X   Fake X nodes and ignore NUMA setup of the actual machine.
+  numa=fake=CMDLINE
+               If a number, fakes CMDLINE nodes and ignores NUMA setup of the

+               depending on the sizes and coefficients listed.  For example:

+               gives two 512M nodes, a 1024M node, and four 256M nodes.  The
+               remaining system RAM is allocated to an additional node.
