Selecting a migration network for {a-virt} provider

You can select a default migration network for {a-virt} provider in the {ocp} web console to improve performance. The default migration network is used to transfer disks to the namespaces in which it is configured.

After you select a transfer network, associate its network attachment definition (NAD) with the gateway to be used by this network.

If you do not select a migration network, the default migration network is the pod network, which might not be optimal for disk transfer.

Note	You can override the default migration network of the provider by selecting a different network when you create a migration plan.

Procedure

1. In the {ocp} web console, click Migration > Providers for virtualization.

2. Click the {virt} provider whose migration network you want to change.

   When the Providers detail page opens:

3. Click the Networks tab.

4. Click Set default transfer network.

5. Select a default transfer network from the list and click Save.

6. Configure a gateway in the network used for {project-short} migrations by completing the following steps:

   1. In the {ocp} web console, click Networking > NetworkAttachmentDefinitions.

   2. Select the appropriate default transfer network NAD.

   3. Click the YAML tab.

   4. Add forklift.konveyor.io/route to the metadata:annotations section of the YAML, as in the following example:

      apiVersion: k8s.cni.cncf.io/v1
      kind: NetworkAttachmentDefinition
      metadata:
        name: localnet-network
        namespace: mtv-test
        annotations:
          forklift.konveyor.io/route: <IP address> # (1)

      1. The NetworkAttachmentDefinition parameter is needed to configure an IP address for the interface, either from the Dynamic Host Configuration Protocol (DHCP) or statically. Configuring the IP address enables the interface to reach the configured gateway.

   5. Click Save.
