Minimum No of cores

Hi Guys

I want to install portworx on my openshift on premise cluster.
For resource requirement I am referring below document:

Just want to conferm whether no of CPUs given here "4 cores minimum, 8 cores recommended
" are virtual cores or Physical ?

Virtual cores are expected, same is valid for the physical as well. Note: these are the bare minimum, your mileage (needs) can be higher.
