Retrieve Hyper-V Hosts and Machines

Hi,

I am trying to retrieve from Altiris Inventory Hyper-V server machine and hosts. We have deployed Sever Inventory Plugin and I was expecting to have all Host Server and Virtual machines, but I am quite confussed. In our company, Hypoer-V management is done through SCCM, so our INV_VM_XXXXXX tables are empty.

The best approach I have found is with this query:

SELECT DISTINCT [NODE NAME] AS HOST, REPLACE([Resource Name],'VIRTUAL MACHINE','') AS GUEST
FROM Inv_Associate_Node_To_Active_Resource
WHERE  [Resource Name] LIKE '%VIRTUAL%MACHINE%' AND [Resource Name] NOT LIKE '%CONFIGURATION%' 
ORDER BY [Node Name]

But I am not happy as the query results are good but it seems there are a lot of missing machines.

Any ideas or suggestions?

Thanks in advance
