See `man virsh`, an exceprt here:

  nodeinfo
    Returns basic information about the node, like number and type of CPU, and
    size of the physical memory. The output corresponds to virNodeInfo
    structure. Specifically, the "CPU socket(s)" field means number of CPU
    sockets per NUMA cell. The information libvirt displays is dependent upon
    what each architecture may provide.

For better info you should look at `virsh capabilities`, look for the
`<topology/>` XML node.  Shorthand command would be:

  virsh capabilities | xpath -e '/capabilities/host/topology' -q

HTH,
