Do Hyper-V guests see multiple CPUs (sockets) or multiple CPU cores when assigned more than 1 vCPU?

hyper-v-server-2008-r2

I have SQL Server 2008 Express running on Hyper-V based virtual machine with two vCPU-s. I've just been reading up on SQL Server 2012 Express and noticed that it's CPU is "Limited to lesser of 1 Socket or 4 cores" (http://msdn.microsoft.com/en-us/library/cc645993(v=SQL.110).aspx)

My question is how do the SQL Server 2012 limits on CPUs/Cores translate into vCPU-s? Are they "processors" or are they "cores"?
