      Hi!
      I've gotten myself into a bit of a mess I guess and I need help to resolve it. I changed storage on one of my host, and that meant that I did not power down the host correctly. But now, when I try to forget the host, a running VM does not let me remove the host.

      The problem:

      1. The host is "running" even though it is not connected.
      2. It has a "running" ghost VM
      3. The VM has a GPU attached
      4. Trying to shut the VM down results in the host offline error message.

      How can I resolve this issue?

        @kassebasse , please clarify a few things:

        1. When you sat that the host is "running", do you mean that the host is powered on?
        2. Is there an SR on the host?
        3. Is there any data on the host that you want to keep?
        4. What are you trying to accomplish by forgetting the host?

          1. I mean that Xen Orchestra sees the host as running. Even though it should show offline. The host has been reinstalled, due to upgrading the storage (local disks only)

          2. There is only a local SR on the host that has been totally wiped (meaning that the operating system of the host is no longer existing and the disks are removed long ago)

          3. All the important VM:s has already been migrated to another host. This host does no longer exist, therefore I wonder why Xen Orchestra shows it running and powered on.

          4. I am just trying to remove the host, because it is no longer exists. The host has been completely wiped, and rejoined again as another host (because of a fresh reinstallation)

            In that case, try

            xe host-declare-dead

            You will need the prior UUID of the host, that is, the UUID assigned to the host before you reinstalled xcp-ng.
            xe host-list will provide that.

            Read the warnings about host-declare-dead carefully.
