Using groups helps you to organize the list of machines.
For example, you can create a separate group for each department in your organization. You can then perform deployment to some or all machines of a department by selecting them in the corresponding group.
Each machine can be a member of one or more groups.
To create a group, click Create group on the toolbar, and then type the name of the group.
To add one or more machines to a group, select them in the list, click Add to group on the toolbar, and then select the group to add the machines to.
A group itself cannot be specified for deployment.
To create a deployment task for all machines that are currently in a group, right-click the group, and then click Deploy image. Subsequent changes to the group do not affect the list of machines in the deployment task.
In addition to the groups you create, there is the All machines built-in group. It contains the entire list of machines.
