On an x86-based system, a CPU core (no hyperthreading enabled) or a CPU thread (hyperthreading enabled) within a core is presented as a physical CPU by the hypervisor or the bare metal operating system. vCPUs (virtual CPUs) are exposed to the guest virtual machine as CPUs: the guest schedules applications on these vCPUs, and the hypervisor schedules these vCPUs over the physical CPU cores or threads. All vCPUs from a guest are symmetrical. Oracle VM Server treats these equally, as long as scheduling parameters such as using CPU pinning have not changed

This document tells how to get vcpu counts in Oracle VM Server.
