Sql-server – Why is SQL Server only able to grab 1Gb of memory

Running SQL Server 2008R2 STD 64bit edition on Windows 2008 R2 64 bit edition.

The Windows server is a Hyper-V VM with its memory set as follows

When I run the following query;

SELECT
[physical_memory_in_bytes] AS [PhysMemBytes],
[physical_memory_in_use_kb] AS [PhysMemInUseKB],
[available_physical_memory_kb] AS [PhysMemAvailKB],
[locked_page_allocations_kb] AS [LPAllocKB],
[max_server_memory] AS [MaxSvrMem],
[min_server_memory] AS [MinSvrMem]
FROM
sys.dm_os_sys_info
CROSS JOIN
sys.dm_os_process_memory
CROSS JOIN
sys.dm_os_sys_memory
CROSS JOIN (
SELECT
[value_in_use] AS [max_server_memory]
FROM
sys.configurations
WHERE
[name] = 'max server memory (MB)') AS c
CROSS JOIN (
SELECT
[value_in_use] AS [min_server_memory]
FROM
sys.configurations
WHERE
[name] = 'min server memory (MB)') AS c2

It gives the output below;

Task Manager shows the same 1Gb in use for the sqlserver.exe process

I do not understand why SQL Server is not grabbing the minimum or maximum memory set in SQL server when the VM is configured with dynamic memory and able to grow to 16Gb?
