Configuring and viewing IP addresses¶

You can configure an IP address when you create a virtual machine (VM). The IP address is provisioned with cloud-init. View the IP address of a VM by using the OpenShift Container Platform web console or the command line. The network information is collected by the QEMU guest agent.

Configuring a static IP address when creating a virtual machine by using the web console¶

You can configure a static IP address when you create a virtual machine (VM) by using the web console. The IP address is provisioned with cloud-init.

Prerequisites

• The virtual machine is connected to a secondary network.

Procedure

1. Navigate to Virtualization → Catalog in the web console.
2. Click a template tile.
3. Click Customize VirtualMachine.
4. Click Next.
5. On the Scripts tab, click the edit icon beside Cloud-init.
6. Select the Add network data checkbox.
7. Enter the ethernet name, one or more IP addresses separated by commas, and the gateway address.
8. Click Apply.
9. Click Create VirtualMachine.

Configuring an IP address when creating a virtual machine by using the CLI¶

You can configure a static or dynamic IP address when you create a virtual machine (VM). The IP address is provisioned with cloud-init.

Prerequisites

• The virtual machine is connected to a secondary network.
• You have a DHCP server available on the secondary network to configure a dynamic IP for the virtual machine.

Procedure

• Edit the spec.template.spec.volumes.cloudInitNoCloud.networkData stanza of the virtual machine configuration:
  • To configure a dynamic IP address, specify the interface name and enable DHCP:
    yaml

    apiVersion: kubevirt.io/v1
    kind: VirtualMachine
    metadata:
      name: <interface_name>
      kind: VirtualMachine
    spec:
    # ...
      template:
      # ...
        spec:
          volumes:
          - cloudInitNoCloud:
              networkData: |
                version: 2
                ethernets:
                  eth1:
                    dhcp4: true
        # ...

  • To configure a static IP, specify the interface name and the IP address:
    yaml

    apiVersion: kubevirt.io/v1
    kind: VirtualMachine
    metadata:
      name: <interface_name>
      kind: VirtualMachine
    spec:
    # ...
      template:
      # ...
        spec:
          volumes:
          - cloudInitNoCloud:
              networkData: |
                version: 2
                ethernets:
                  eth1:
                    addresses:
                    - 10.10.10.14/24
        # ...

Viewing the IP address of a virtual machine by using the web console¶

You can view the IP address of a virtual machine (VM) by using the OpenShift Container Platform web console.

Procedure

1. In the OpenShift Container Platform console, click Virtualization → VirtualMachines from the side menu.
2. Select a VM to open the VirtualMachine details page.
3. Click the Details tab to view the IP address.

Viewing the IP address of a virtual machine by using the CLI¶

You can view the IP address of a virtual machine (VM) by using the command line.

Prerequisites

• You have installed the OpenShift CLI (oc).

Procedure

• Obtain the virtual machine instance configuration by running the following command:
  terminal

  $ oc describe vmi <vmi_name>

  Example output:

  yaml
