### Adding and Deleting Pool Members A VDI pool can contain different types of members. These could be all available guest VMs, specific guest VMs, and guest VMs created from a template. To add a member to a pool: Select a pool in the Pools list. In the Tasks drop-down menu above the Members list (the upper right-hand corner of the Members area), click Add and choose a member type from the following list: All guest VMs in Host. All guest VMs that are located on a given VDI provider. After clicking this options, you'll be able to select a VDI provider. Note: Parallels does not recommend to use this type because there's a possibility that guest VMs with unsupported OS will be added (e.g. Linux, HALB etc). If you need to use this type, please do it carefully or use a wildcard with appropriate guest VMs names. Guest VM. A specific guest VM located in the Farm. After clicking this options, you'll be able to select a guest VM from the list. Resource pool. A group of guest VMs that were natively configured in the hypervisor as a pool. Please note that a hypervisor may use a different term for pools (e.g. "resource pools"). After clicking this option, you'll be able to select a resource pool from the list, if any are available. Template. Guest VMs that are automatically created from a template. After selecting this option, you'll be able to select a template. For more information about templates, refer to Managing Templates. After you click one of the above menu items, you will be presented with the list of the available hosts, guest VMs, or templates from which you can make your selection. Note: To avoid issues with overlapping members, a given pool can have members of the same type only. For example, if the first member that you add to a pool is a guest VM, any additional member can be a guest VM, but not a template, Resource pool, or all guest VMs on a specified host. If you want to use members of different types, you must create a separate pool for each member type (i.e. one pool for guest VMs, another pool for templates, etc.). This requirement is enforced in the UI by disabling the member type choices once the first member is added to a pool. To delete a member from a pool, select the pool, then select a pool member you wish to delete, and then click Tasks > Delete.
