Create a Windows VM

About this task

This section provides an example of deploying a WindowsServer-based VM with KubeVirt.

The example uses:

• A Windows Server 2019 image pre-installed in a qcow2 type image

  • See https://superuser.openstack.org/articles/how-to-deploy-windows-on-openstack/ for information on how to create such an image using VirtualBox and starting with a Windows Server 2019 ISO image and Fedora VirtIO drivers.

  • In order to make things easier, as part of making this image be sure to:

    • configure a well-known Administrator password,

    • enable Remote Desktop, and

    • enable Cloud-Init.

• The CDI Upload Proxy service to upload the Windows Server 2019 pre-installed qcow2 image into a DataVolume/PVC, for the root disk,

  Note that this image will be larger than previous ubuntu image so will take longer to load.

• Explicit resource request for 4x CPUs and 8G of Memory

• Multus and SR-IOV CNIs in order to add an additional SR-IOV-based interface.

  These allow the VM to be assigned a unique IP Address from the IP Subnet attached to the SR-IOV-based interface.

• Connect with the graphical console interface via Virtctl in order to extend the root disk and configure the IP Interface on the SRIOV-based interface.

• Remote Desktop (RDP) from a remote workstation to the Windows VM’s unique IP Address on the IP Subnet attached to the SR-IOV-based interface.

This example assumes the same infrastructure changes as in the previous Ubuntu VM example have been done here. i.e., SR-IOV interfaces connecting to a 10.10.186.0/24 network on vlan-id=20 have been configured on all hosts, and a NetworkAttachmentDefinition, 186-subnet, has been created to this network.

From a remote workstation that you have configured kubectl, virtctl and virt-viewer, follow the procedure below to create the Windows VM, login to the graphical console and configure the VM’s interface on the 10.10.186.0/24 network. Finally, RDP to the VM from a remote workstation.

Procedure

1. Use virtctl and the CDI Upload Proxy service to load the Windows Server 2019 qcow2 image into a new DataVolume of size 500G, in the stx-lab namespace.

   $ virtctl image-upload dv stx-lab-winserv-test-disk --namespace stx-lab --insecure \
      --access-mode ReadWriteOnce --size 100Gi --image-path \
      /home/sysadmin/admin/kubevirt/images/winserv2019.qcow2 \
      --uploadproxy-url https://admin.starlingx.abc.com:32111
   

2. Create the yaml file defining the VirtualMachine CRD instance

   $ cat <<EOF > stx-lab-winserv-test-vm.yaml
   apiVersion: kubevirt.io/v1alpha3
   kind: VirtualMachine
   metadata
     labels:
       kubevirt.io/vm: stx-lab-winserv-test
     name: stx-lab-winserv-test
     namespace: stx-lab
   spec:
     running: true
       template:
         metadata:
           labels:
             kubevirt.io/vm: stx-lab-winserv-test
         spec:
           domain:
             devices:
               disks:
               - disk:
                   bus: virtio
                 name: myrootdisk
               interfaces:
               - masquerade: {}
                 name: default
               - name: 186-subnet
                 sriov: {}
             machine:
               type: q35
             resources:
               requests:
                 cpu: 4
                 memory: 8G
           terminationGracePeriodSeconds: 0
           networks:
           - name: default
             pod: {}
           - multus:
               networkName: stx-lab/186-subnet
             name: 186-subnet
           volumes:
          - name: myrootdisk
            dataVolume:
              name: stx-lab-winserv-test-disk
   EOF
   

3. Apply the configuration.

   $ kubectl apply -f stx-lab-winserv-test-vm.yaml
   

4. Connect to the graphical console, extend the root disk, and configure the VM’s interface on the 10.10.186.0/24 network.

   $ virtctl -n stx-lab vnc --kubeconfig="/home/jdoe/.kube/config" stx-lab-winserv
   

   This command launches Windows graphical console.

   1. Login with well-known Administrator password set when the Windows Server 2019 qcow2 image was created.

   2. Extend the root disk to fully use the space on the root disk.

      Computer Management > Storage > Disk Management > Extend Volume (on the C: drive)

   3. Configure the second ethernet adapter (SRIOV-based Interface).

      For example:

      • with static ip address in 10.10.186.0/24 subnet

      • with the gateway ip address and

      • with DNS address (10.10.186.130)

   4. Logout of graphical console.

Results

You can now RDP to the Windows VM using the 10.10.186.<nnn> IP Address.
