If i have 2 physical processors with 4 cores each and to maintain a 1:1 mapping between virtual to physical cores, i cannot give more than 8 cpus in total to all virtual machines?

In this environment, there is an exchange vm that is running on the above physical core specification.  In total, there are 22 vpus to assigned to all the virtual machines running on this host.

I know that vmware / hyper-v best practice for exchange is 1:1.  I was told today that the exchange virtual machine is running on a one-to-one mapping.

The other thing is that hyper-threading is enabled on the physical host giving it 16 cores.  I understand that virtual to physical core mapping isn't based on hyper-threaded cores but actual physical cores.

how is this possible that the exchange vm is running on 1:1
