A NUMA cell in libvirt terms is a NUMA node in other terms.  Unfortunately
the word "node" is horribly overloaded in libvirt, so we choose another name.

For processors that support hyperthreading, this is the number of hyperthreads
they have per core.  On a machine that doesn't support hyperthreading, this
will be 1.
