Though no machine supports all these 7 levels yet, these 7 levels have the strict containment relationship and together form the generic CPU topology representation of QEMU. Also, note that the maxcpus is calculated by multiplying all 7 levels: maxcpus = drawers * books * sockets * dies * clusters * cores * threads. To cover this code path, it is necessary to test the full topology case (with all 7 levels). This also helps to avoid introducing new issues by further expanding the CPU topology in the future.
