    Hi,

    after adding several Hyper-V hosts to the VMM we see a new note per VM called ""#CLUSTER-INVARIANT#:{GUID}". VMs on an attached ESX farm are showing an attribute "ClusterInvariantVMMId" too. What is the whole purpose of that?

     

    Regards

    Wolfgang

    hi there,

     

    VMM adds these values to those fields so that we can associate a specific VM with VMM. If someone were to move this VMM from one host to another without VMM having any knowledge of the move, we use these fields to reassociate the VM.

     

    Please don't edit or delete these values. In general VMM will overwrite them with the correct values.

     

    cheers.

    I like Michael's explanation but what do the words "CLUSTER INVARINAt" mean?

    As Michael explained above, the GUID does not change (i.e. is invariant) if the VM moves between hosts. The primary scenario where this occurs is when a VM migrates between hosts in a cluster, hence "cluster invariant".
