Deleting network adaptor from VM deleting virtual machine from Hyper-v host. RRS feed

  • Question

  • We are running VMM in a cluster environment, recently we migrated VMs from VMM 2012 to VMM 2019, all hyper-v hosts are now running Windows Server 2019, We are facing very strange issue which is if we turn off any VM from cluster, go to settings and remove network adaptor from that VM, we are unable to start that machine, settings window also doesnt open to readd the deleted network adaptor, upon investigation we found that VM is actually deleting from hyper-v host, vm is showing from cluste console. It is only happening with migrated vm, if I create new VM on cluster, shutdown it and remove network adaptor, we are able to turn it ON.

  • Hello,

    If the VM is showing from cluster console, can you turn it on from the cluster console?

    In addition, have you also check the existence of VHDX files on the storage? 

    If the vNIC is not removed, can the VM be turned off and on without errors?

    By the way, what's the guest OS running in the VM?

    Best regards,

    Andy Liu

  • Hello,

    Could you please install the most recent updates for the guest OS, which can help update the integration service , and then try the operation again?

    I'm concerned that this issue occurred because the version of integration service is not update to date.

    Please click the following link for more details about integration service on the Hyper-V host.
