What exactly is the CPU Average field in VMM 2012 showing me?

I'm running Server 2008 R2 with VMM 2012. My server has 2x16 core CPUs installed.

An example virtual machine has 4 virtual processors, and shows 20% CPU usage. Is that:

20% of the entire system's available CPU power?
20% of 4 of the 32 core's CPU power?
20% of one core's CPU? (in which case it could go as high as 400%)
Something else entirely?

How can I tell how much of the entire system's CPU power is being used (all 32 cores)?

Edit: Well, I can tell for sure it's not 20% of the entire system's CPU power - since the entire server's CPU averages add up to well over 100% right now.
