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
