Tags enable you to identify your resources in new ways. Tags are like keywords or labels, and they allow you to rearrange your view of resources within XenCenter depending on criteria that are important to you, such as application, location, cost center, owner, or lifecycle stage.
You make up tags when you need them and you can use as many as you like, and you can build searches based on your tags, for example "all Windows 7 test machines located in Cambridge".
Click on the General tab for a resource to see the tags currently assigned to that resource and to add and remove tags.
The simplest way to assign an existing tag to a resource is by dragging and dropping it onto the tag in the Resources pane (Folder View). You can drag and drop resources from within the Resources pane in Folder View, and also from the search results list on the Search tab.
You can also assign an existing tag or a new tag to a resource using the Edit tags dialog box:
The simplest way to untag (remove a tag from) a resource is tag is by selecting it in the Resources pan (Folder View), right-clicking and then clicking Untag object on the shortcut menu.
You can also untag a resource from the Edit Tags dialog box:
You can view all the tags you have assigned as a tag cloud, where the size of the tag reflects the number of times it is used. For example:
To view your XenCenter tag cloud, click on the top-level XenCenter item in the Resources pane and then click on the Tags tab.
When you click a tag in your tag cloud, a list of all the resources with that tag is displayed on the Search tab.
