Back in the VEPU121 enablement series[1] it had been decided to not
expose multiple identical cores yet, because there is no infrastructure
yet in the kernel to schedule multiple userland processes on multiple
cores, or (more relevant for your usecase) to even combine two cores to
reach 8K support.
