Selecting a migration network for a source provider

Select a migration network to reduce risk to the VMware environment and to improve migration performance.

By default, Forklift selects the management network of a source provider. However, using the management network for migration can result in poor performance because the network might not have sufficient bandwidth. This situation can have a negative effect on the VMware platform because the disk transfer operation might saturate the network and impede communication between vCenter and the ESXi hosts.

Prerequisites
  • The migration network must have sufficient throughput, minimum speed of 10 Gbps, for disk transfer.

  • The migration network must be accessible to the KubeVirt nodes through the default gateway.

    Note

    The source virtual disks are copied by a pod that is connected to the pod network of the target namespace.

  • The migration network must have jumbo frames enabled.

  • You must have administrator privileges for each ESXi host.

Procedure
  1. In the web console, navigate to Providers and click VMware.

  2. Click the host number in the Hosts column beside a VMware provider to view a list of hosts.

  3. Select one or more hosts and click Select migration network.

  4. Complete the following fields:

    • Network: Select the migration network.

      You can clear the migration network selection by selecting the default management network.

    • ESXi host admin username: Specify the ESXi host admin user name, for example, root.

    • ESXi host admin password: Specify the ESXi host password.

  5. Click Save.

  6. Verify that the status of each host is Ready.

    If a host status is not Ready, the host might be unreachable on the migration network or the credentials might be incorrect. You can modify the host configuration and save the changes.

The migration network is displayed in the list of ESXi hosts.
