Live migration limits and timeouts

• Configuring live migration limits and timeouts
• Cluster-wide live migration limits and timeouts

Apply live migration limits and timeouts so that migration processes do not overwhelm the cluster. Configure these settings by editing the HyperConverged custom resource (CR).

Configuring live migration limits and timeouts

Configure live migration limits and timeouts for the cluster by updating the HyperConverged custom resource (CR), which is located in the openshift-cnv namespace.

Procedure

• Edit the HyperConverged CR and add the necessary live migration parameters.

  $ oc edit hco -n openshift-cnv kubevirt-hyperconverged

  Example configuration file

  apiVersion: hco.kubevirt.io/v1beta1
  kind: HyperConverged
  metadata:
    name: kubevirt-hyperconverged
    namespace: openshift-cnv
  spec:
    liveMigrationConfig: (1)
      bandwidthPerMigration: 64Mi
      completionTimeoutPerGiB: 800
      parallelMigrationsPerCluster: 5
      parallelOutboundMigrationsPerNode: 2
      progressTimeout: 150

  1	In this example, the spec.liveMigrationConfig array contains the default values for each field.

  You can restore the default value for any spec.liveMigrationConfig field by deleting that key/value pair and saving the file. For example, delete progressTimeout: <value> to restore the default progressTimeout: 150.
