Manage virtual machines

This page describes how to manage virtual machines on Google Distributed Cloud Edge running VM Runtime on Google Distributed Cloud. You must be familiar with VM Runtime on GDC before completing the steps on this page. For a list of supported guest operating systems, see Verified guest operating systems for VM Runtime on GDC.

To learn how virtual machines serve as an essential component of the Distributed Cloud platform, see Extending GKE Enterprise to manage on-premises edge VMs.

Local control plane clusters support virtual machine webhooks. This allows Distributed Cloud Edge to validate user requests made to the local Kubernetes API server. Rejected requests generate detailed information on the reason for rejection.

Enable VM Runtime on GDC support on Distributed Cloud Edge

By default, VM Runtime on GDC virtual machine support is disabled on Distributed Cloud Edge. To enable it, complete the steps in this section. The instructions in this section assume that you have a fully functioning Distributed Cloud Edge cluster.

The VMRuntime resource that configures VM Runtime on GDC support on Distributed Cloud Edge also configures GPU support on your cluster by using the enableGPU parameter. Make sure that you configure the two parameters according to your workload needs. You do not have to enable GPU support to enable VM Runtime on GDC support on your Distributed Cloud Edge cluster.

The following table describes the available configurations:

enable value	enableGPU value	Resulting configuration
false	false	Workloads run only in containers and cannot use GPU resources.
false	true	Workloads run only in containers and can use GPU resources.
true	true	Workloads can run on virtual machines and in containers. Both types of workloads can use GPU resources.
true	false	Workloads can run on virtual machines and in containers. Neither type of workload can use GPU resources.

If you have already enabled GPU support, modify the VMRuntime resource to add the enable parameter, set its value to true, and then apply it to your Distributed Cloud Edge cluster.

Enable the VM Runtime on GDC virtual machine subsystem

Depending on the type of cluster on which you want to enable the VM Runtime on GDC virtual machine subsystem, do one of the following:

• For Cloud control plane clusters, you must manually create the VMRuntime resource.
• For local control plane clusters, you must edit the existing VMRuntime resource.

To enable the VM Runtime on GDC virtual machine subsystem, complete the following steps:

1. Depending on the target cluster type, create or modify the VMRuntime custom resource with the following contents and apply it to your cluster:

   apiVersion: vm.cluster.gke.io/v1
   kind: VMRuntime
   metadata:
     name: vmruntime
   spec:
     # Enable Anthos VM Runtime support
     enabled: true
     # vmImageFormat defaults to "raw" if not set
     vmImageFormat: "raw"
   

   Do not change the value of the vmImageFormat parameter. Distributed Cloud Edge does not support any other virtual disk formats.

   This process typically takes several minutes to complete.

2. Use the following command to verify that the VMRuntime custom resource has been applied to your cluster:

   kubectl get vmruntime -o yaml
   

   The command returns output similar to the following example:

    - apiVersion: vm.cluster.gke.io/v1
      kind: VMRuntime
      metadata:
        name: vmruntime
        ...
      spec:
        enabled: true
        vmImageFormat: raw
      status:
        ...
      ready: true
        ...
   

3. Use the following command to verify that VM Runtime on GDC virtual machine support has been enabled on your cluster:

   kubectl get pods -n vm-system
   

   The command returns output showing the VM Runtime on GDC subsystem Pods running on your cluster, similar to the following example:

   NAME                                                READY   STATUS         RESTARTS        AGE

Grant the target namespace access to the Distributed Cloud Edge registry

The steps in this section only apply to Cloud control plane clusters. If you are configuring the VM Runtime on GDC virtual machine subsystem on a local control plane cluster, skip this section.

Before you can create a virtual machine in a namespace, you must grant that namespace access to the Distributed Cloud Edge registry. The registry holds components necessary to create and deploy your virtual machines in the target namespace. Keep in mind that you cannot run virtual machines in namespaces reserved for Distributed Cloud Edge system management. For more information, see Management namespace restrictions.

Complete the following steps to grant your target namespace access to the Distributed Cloud Edge registry:

1. Patch the default service account in the target namespace with the imagePullSecret key named gcr-pull:

   kubectl patch sa default -p "{\"imagePullSecrets\": [{\"name\": \"gcr-pull\"}]}" -n NAMESPACE
   

   Replace NAMESPACE with the name of the target namespace.

2. Refresh the associated secret in the target namespace:

   # Delete existing secret.
   kubectl delete secret gcr-pull -n NAMESPACE --ignore-not-found
   # Copy the new secret to the target namespace.
   kubectl get secret gcr-pull -n vm-system -o yaml | sed "s/namespace: vm-system/namespace: NAMESPACE/g" | kubectl apply -f -
   

   Replace NAMESPACE with the name of the target namespace.

   The secret expires after one hour. You must manually refresh it after it expires.

Install the virtctl management tool

You need the virtctl client tool to manage virtual machines on your Distributed Cloud Edge Cluster. To install the tool, complete the following steps:

1. Install the virtctl client tool as a kubectl plugin:

   export VERSION=v0.49.0-anthos1.12-gke.7
   gcloud storage cp gs://anthos-baremetal-release/virtctl/${VERSION}/linux-amd64/virtctl /usr/local/bin/virtctl
   cd /usr/local/bin
   sudo ln -s virtctl kubectl-virt
   sudo chmod a+x virtctl
   cd -
   

2. Verify that the virt plugin is installed:

   kubectl plugin list
   

   If the plugin has been successfully installed, the command's output lists kubectl-virt as one of the plugins.

Provision a virtual machine on Distributed Cloud Edge with raw block storage

This section provides configuration examples that illustrate how to provision a Linux virtual machine and a Windows virtual machine on a Distributed Cloud Edge cluster with raw block storage. The examples use block storage instantiated as a PersistentVolume.

Limitations of using raw block storage

The following limitations apply when running virtual machines with raw block storage on Distributed Cloud Edge:

• The OSType field is not supported in VirtualMachine resource specifications on Cloud control plane clusters. Because of this, only console and vnc methods are supported for accessing virtual machines running on Cloud control plane clusters.
• You cannot create a virtual machine on a Distributed Cloud Edge cluster directly by using the kubectl virt command because Distributed Cloud Edge does not provide file system storage to virtual machines.
• Block storage PersistenVolumeClaim resources do not support the qcow2 disk image format.
• The Containerized Data Importer (CDI) plug-in does not support DataVolume resources on block storage because the plug-in's scratch space only works on file system storage. For more information, see Scratch space.

Provision a Linux virtual machine on Distributed Cloud Edge with raw block storage

The following example illustrates how to provision a Linux virtual machine with raw block storage running Ubuntu Server 22.04. The installation source is the Ubuntu Server 22.04 ISO disc image.

     name: win-vm #  Propagate the virtual machine name to the VMI
   spec:
     osType: Windows
     compute:
       virtualMachineTypeName: my-vmt
     interfaces:
       - name: eth0
         networkName: pod-network

         boot: true
       - virtualMachineDiskName: windows-iso-disk
       - virtualMachineDiskName: win-virtio-driver
   

   The osType field only applies to local control plane clusters. It is required on local control plane clusters to configure the following features:

   • Passwordless SSH access to the virtual machine
   • Configure VM startup routines

7. Install Windows on the virtual machine:

   1. Wait for the importer Pod to download the Windows installation disc image.

   2. Check the status of the virtual machine:

      kubectl get gvm VM_NAME
      

      Replace VM_NAME with the name of the virtual machine—win-vm in this example.

   3. Complete the Windows installation by following the steps in Connect to Windows VM and complete OS install.

8. Clean up:

   1. Stop the virtual machine:

      kubectl virt stop VM_NAME
      

      Replace VM_NAME with the name of the virtual machine—win-vm in this example.

   2. Complete the steps in Detach the ISO image and drivers disk.

Provision a virtual machine on Distributed Cloud Edge using virtctl

If you do not require the customization provided by writing your own resource specifications for your virtual machines, you can provision a virtual machine on Distributed Cloud Edge using the virtctl command-line tool as described in Create a VM.

Manage virtual machines running on Distributed Cloud Edge

For instructions about managing virtual machines running on Distributed Cloud Edge, see the following VM Runtime on GDC documentation:

• Connect to VMs
• List and view VMs
• Manage power state
• Edit a VM
• Delete a VM
• View VM console logs

To manage virtual machines running on local control plane clusters, you must first Configure kubectl connectivity.

Configure the ttyS0 device for serial console access to Linux virtual machines

If you plan to access your Linux virtual machines by using the serial console (kubectl virt console), make sure that the ttyS0 serial console device has been configured on the guest operating system. To configure this device, complete the following steps:

1. Instantiate the ttyS0 serial device in the system:

   setserial -g /dev/ttyS0
   

2. Configure the grub bootloader to use the ttyS0 serial device by adding the following lines to your /etc/default/grub configuration file. The first line replaces your existing GRUB_CMDLINE_LINUX variable.

   GRUB_CMDLINE_LINUX='console=tty0 console=ttyS0,19200n8'
   GRUB_TERMINAL=serial
   GRUB_SERIAL_COMMAND="serial --speed=19200 --unit=0 --word=8 --parity=no --stop=1"
   

3. Apply the new grub configuration to your boot sector:

   update-grub
   

4. Restart the virtual machine.

Disable VM Runtime on GDC on Distributed Cloud Edge

Follow the steps in this section to disable VM Runtime on GDC on Distributed Cloud Edge. Before you can disable VM Runtime on GDC on Distributed Cloud Edge, you must stop and delete all the virtual machines on your Distributed Cloud Edge cluster as described in Delete a VM.

To disable VM Runtime on GDC on Distributed Cloud Edge, modify the VMRuntime custom resource by setting the enabled spec parameter to false as follows, and then apply it to your cluster:

apiVersion: vm.cluster.gke.io/v1
kind: VMRuntime
metadata:
  name: vmruntime
spec:
  # Disable Anthos VM Runtime
  enabled: false
  # vmImageFormat defaults to "raw" if not set
  vmImageFormat: "raw"
