When configuring a virtual link using two ABR, say R1 is the ABR that is actually connected to area 0 and R2 is the virtual link router
Is the interface on r2 connected to R1 put into area 0 or does it not have an area?

No you don't place any interfaces on the ABR that is not part of area 0 into area 0 when configuring a virtual link. Think of a virtual link as an extension of area 0, or an area 0 tunnel through another area. It is important to note that the virtual link command expects you to use the router-id of the ABR routers invilved in the virtual link, so it's a good idea to hard code the router id with the "router-id" command in router configuration mode.
