Stolen time reporting through vmstat/top only works on xen and kvm hypervisors, it wasn't implemented for vmware. It actually looks like it was finally submitted for linux v5.7 (https://lore.kernel.org/lkml/20200331100353.ga37...@gmail.com/). If you want those numbers for older kernels, fetch this repository: https://github.com/dagwieers/vmguestlib and run vmguest-stats. You'll also need open-vm-tools installed. Have used this many times in the past and the numbers are good.
