    Scenario: Two VM servers (for example, A & B) have two distinct IP addresses. During the first scan, Discovery skips Server A (Reason: Optimized on Initial Scan) and infers Server B. During the second scan, Discovery skips Server B (Reason: Optimized on Initial Scan) with "Inferred Node" as Server A.


    A similar scenario is when discovery of some VM servers is "Skipped" on multiple IP's even though the server has only one IP.

    The affected VM's were apparently cloned with the same UUID and therefore have the same serial number.  In this case, Discovery will think both the original and the clone are the same VM, and will collapse them into the same host. The other IP's are then skipped.


    The solution is make sure that VM's are generated with a unique UUID.
