confused configure processors and cores

I'm confused how to allocate values for Processors and Cores to virtual machines and how the relate to the physical machine.

I'm running a quad core I7 - I assume this means 1 processor with 4 cores. But then what about virtual processors on the physical machine?

Can anyone help with my understanding and what to allocate the the virtual machines (max and min)

Thanks.

For the virtual machine, there is no practical difference between assigning multiple processors or multiple cores.  This option was added several versions back, to make it easier for people licensing certain OS's or applications - some are licensed per socket, others per core.  Performance wise, there should be no difference - the virtual machine will still use one CPU resource per processor/core you specify.

Note that you should never assign more than (n-1) virtual CPUs to any VM, otherwise you may starve your host.  In this environment, typically less is more.
