I.e, each package has two NUMA nodes, and the two numa nodes share
the same core ID set (0-6), which means parsing the cores number
from sysfs doesn't work in this case.

I would like to tweak this test to output more information; instead of
just outputting nodes and cores, we should also add sockets and threads
into the test output, as well as VIR_NODEINFO_MAXCPUS(nodeinfo) (yes,
this means updating all three test files); doing so will help us ensure
that the numbers we are printing make sense.
But I also plan to add a test-4 on a machine with a cpu that was
hot-unplugged, to show an instance where CPUs is less than maxcpus, so I
can make those changes in my patch. Which means I'm fine with your
patch going in, as-is.
ACK.
Thanks, so I pushed it.

Osier
