[Observium] win srv in VM not listed as srv ( rename device, it disappears from "Servers" view )

Hi

I have a Windows 2003 server, virtual, not listed under "Servers" view.

We have many Windows 2003 servers, most of all as guests under Vmware ESX.

One of this is listed only in the "All devices" view.

To the developers : please, can you give me any insight : how does Observium decide the kind of device ?

What I have to check to pinpoint the problem ?

Best regards, Sala
