# Distribution

Use the **Distribution** page to configure template distribution. Note that this page will only appear if the source VM is created with Microsoft Hyper-V or VMware vCenter. 

## Microsoft Hyper-V 

To configure template distribution:

1. Select the **Enable multi-provider template distribution** option.
2. In the **Available** list, select one or more providers and click **Add** (or **Add all** to add all available providers). Note that only providers of the same type and subtype as the source VM are displayed in this list.
3. In the **Number of providers for concurrent distribution** field, specify the number of concurrent distribution operations. The template is distributed to target hosts using Hyper-V Live Migration, which first exports the virtual machine to a file and then moves it to the destination host. For each host in the **Target** list, a Live Migration operation must be performed. The number specified here dictates how many network copy operations should be started at the same time. The larger the number, the more network resources will be required. Note that virtual machine exports (the first step of Live Migration) are always done one VM at a time, so the number you specify here affect only the copy operations.

{% hint style="info" %}
**Note:** The **Enable multi-provider template distribution** setting cannot be modified (selected or cleared) once the template is created. If later you decide to turn it on or off (enable or disable the feature), you will need to delete and re-recreate the entire template. You can, however, add or remove Providers to/from an existing template.
{% endhint %}

When done, click **Next** to proceed to the next wizard page.

For the description of this feature and requirements, please see [**Multi-provider template distribution**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/virtual-desktop-infrastructure-vdi/manage-vdi/manage-templates-vdi/multi-provider-template-distribution.md).

## VMware vCenter

Datastores are containers that store VMware virtual machines. By default, all hosts created from a template are stored in the same datastore as the template. You can choose to create hosts in several datastores, which will ensure that some hosts stay operational even if one datastore fails.

To select datastores for your hosts:

1. Select one of the following:
   * If you want to create all hosts in the datastore that contains the template, select **Use the datastore containing the VM being converted to a template**.
   * If you want to create hosts in several datastores, select **Select additional datastores to use for template distribution**.
2. (Optional) If you selected **Select additional datastores to use for template distribution**, select the datastores in the **Datastores** list. 
3. Click **Next**.
