From Understanding the VAS Reservation (aka MemToLeave) in SQL Server by Jonathan Kehayias this shows you the clerks using VAS in detail:
SELECT type, virtual_memory_committed_kb, multi_pages_kb
FROM sys.dm_os_memory_clerks
WHERE virtual_memory_committed_kb > 0 OR multi_pages_kb > 0
There are no special teachers of virtue, because virtue is taught by the whole community.
