#### Synchronizing Templates With Hardware Nodes

The Hardware Nodes tab under on the application properties page allows viewing the list of all Hardware Nodes an Application is synchronized with. If at least one version of a particular Application is not synchronized with a Hardware Node, the red cross will be displayed in Synchronized column. To synchronize a package set (i.e., synchronize missing package sets) with Hardware Node, check the box next to a Hardware Node name and click the Synchronize button.

Important: You can upload to the Management Node the Virtuozzo for Windows templates only in the .efd format.

To create Containers, OS templates and Applications templates must be installed on a Virtuozzo node that hosts Containers. Templates installation is called synchronization. Templates are distributed on Hardware Nodes as RPM packages, unpacked, and installed.

To register a template on a Hardware Node:

1. Go to Service Director - Virtuozzo Manager - Nodes - <Node>.
2. Click OS Templates/Applications. The list of all OS/applications templates installed on the Hardware Node appears on the screen.
3. Click the Synchronize button.
4. Click Refresh at the top of the page to update the system information.

   Note: You can only synchronize OS templates for Parallels Virtuozzo Containers for Windows versions no older than the 3.5 release.

A template status in the templates list table tells about a template availability and existence on a Hardware Node:

- Registered. A template RPM is absent on a Management Node, but this template configuration file exists in Parallels Business Automation - Standard database.

  Note: A template in a Registered state cannot be synchronized with other Hardware Nodes since a template RPM is missing and a template cannot be installed. To make a template installation on Hardware Node(s) possible, a template RPM must be installed on a Management Node first. Then a template status becomes Installed and its distribution on Hardware Nodes becomes possible.

- Installed. Both a template configuration file and a template RPM exist on a Management Node. A template can be distributed onto any of registered Hardware Nodes.
- Synchronized. A template configuration file and a template RPM exist on a Hardware Node. A template RPM is unpacked, i.e., a template is installed on a Hardware Node.

  Note: If a template was installed on a Hardware Node manually, then Management Node knows nothing about this and keeps a template status as not synchronized. To let the Management Node know about an actual template status, go to the Service Director - Virtuozzo Manager - Nodes, and select the Hardware Node. Click on Applications ot OS templates tab. Check the box next to a template name and click the Update Synchronization State button.
