VM reserved is simply the overall amount of virtual address space the server has reserved. Just because your box has 32 GB does not mean that the SQL Server needs to use all of it if it believes that 1.6 GB is enough for the time being. It will reserve more when it needs to up to the limit you set.

Reserved Memory column shows how much the server has reserved for DAC, and 1 MB is default. Reserved Memory In Use shows 0 because you are not using DAC.

New code box

There's a new way to format code on the site - the red speech bubble logo will automatically format T-SQL for you. The original code box is still there for XML, etc. More details here.
