Prerequisites

• OpenShift Virtualization (KubeVirt) installed.
• ODF (Ceph) running with a StorageClass like ocs-storagecluster-ceph-rbd.
• virtctl installed on your machine.

Step-by-Step Instructions

1️ Create Namespace oc new-project windows-vms

2️ Upload Windows ISO as PVC

virtctl image-upload pvc windows-server-iso \
  --image-path /path/to/WindowsServer.iso \
  --namespace windows-vms \
  --access-mode ReadWriteOnce \
  --storage-class ocs-storagecluster-ceph-rbd \
  --size 10Gi \
  --insecure

3️ Upload VirtIO Driver ISO as PVC Download virtio-win.iso from https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/

virtctl image-upload pvc virtio-drivers \
  --image-path /path/to/virtio-win.iso \
  --namespace windows-vms \
  --access-mode ReadWriteOnce \
  --storage-class ocs-storagecluster-ceph-rbd \
  --size 1Gi \
  --insecure

4️ Create Blank Root Disk as DataVolume (refer windows-rootdisk-dv.yaml)

5 create VM using windows-vm.yaml. Ensure iso,virtIO and root datadisk volume PVC names are correct. Apply it (oc apply -f windows-vm.yaml)

6 Start the VM

virtctl start windows-vm -n windows-vms

7 Install Windows

• Use OpenShift Console → Virtualization → windows-vm → Console.
• At disk selection screen:
  • Click "Load driver".
  • Navigate to:
E:\viostor\2k22\amd64
  • 
(or 2k19/win10 depending on ISO version)
  • Select the .inf file and load the driver.
  • Disk should now be detected.
• Install NW driver from “E:\NetKVM\2k22\amd64”
• Proceed with installation. 8 Optional Cleanup After Install Once Windows is installed:
• Shut down VM:

  virtctl stop windows-vm -n windows-vms
  

• Edit VM YAML to remove:
  • cdrom (Windows ISO)
  • virtio (driver ISO) This prevents re-attaching on every boot. 9 Steps to Reinstall(in case of any error): Stop the VM:

  virtctl stop windows-vm -n windows-vms
  

  Delete the current root disk (if okay to lose current install):

    oc delete dv win-rootdisk -n windows-vms
  

  Recreate the root disk using the same windows-rootdisk-dv.yaml: 
``` oc apply -f windows-rootdisk-dv.yaml

   Start the VM again:
  

  virtctl start windows-vm -n windows-vms

1. Create a template: oc apply -f mssql-benchmark-template.yaml

2. Check template: oc get templates -n windows-vms

3. Create a clone of a PVC (root volume) from a OC console or through YAML

cat <<EOF | oc apply -f -
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mssql-vm-1-rootdisk
  namespace: windows-vms
spec:
  storageClassName: ocs-storagecluster-ceph-rbd
  dataSource:
    name: win2-rootdisk
    kind: PersistentVolumeClaim
    apiGroup: ""
volumeMode: Block
accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 200Gi
EOF

4 .Process the template:

oc process -n windows-vms mssql-benchmark-template-pvc \
  -p NAME=mssql-vm-1 \
  -p NAMESPACE=windows-vms \
  -p PVC_NAME=mssql-vm-1-rootdisk | oc apply -f -

4. Start the VM oc start vm mssql-vm-1 -n windows-vms
