why is the vm reserved so low ?

AWE Allocated       27852800

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.
