Paravirtualisation is a method of running an OS for a non
Popek-and-Golderberg instruction set under a hypervisor. It modifies
the guest OS so that it does not use any privileged instructions
needed by the host OS.

In practice, this means that these are kernels for Xen VMs running on
host hardware that does not support Intel or AMD hardware
virtualisation.

It's nothing to do with VMware at all.
