#### KubeVirt

`kubevirt.migrations` is available since Cozystack v1.6.4. Earlier 1.6 releases ignore it.

| Value | Default | Description |
| --- | --- | --- |
| `kubevirt.migrations` | `{}` | Cluster-wide settings forwarded to `spec.configuration.migrations` on the KubeVirt CR. Set them through the platform Package so they are part of the rendered configuration. An empty or null map leaves KubeVirt's defaults unchanged. |

Example under `spec.components.platform.values`:

```yaml
kubevirt:
migrations:
bandwidthPerMigration: 625M
parallelMigrationsPerCluster: 2
parallelOutboundMigrationsPerNode: 1
```

`bandwidthPerMigration` is a quantity in bytes per second, so `625M` is 625,000,000 bytes/s (5 Gbit/s) per migration. This example allows up to two migrations across the cluster and one outbound migration per node.

#### Internal fields

These fields are managed automatically by the Cozystack operator and should not be modified manually.
