Before you can create a Guest, you need to create a Pool for it; to do this, click on the icon Pool of the top bar, or open the "Guest / Host / Pool" section in the left area of the Dashboard and click the right mouse button on tree view and navigate to "Pools". Then click the "New Pool" .
A window will open to start the creation of the new Pool.
Enter the name of the Pool and click "Next".
You can select the Hosts you want to associate with the new Pool Press "Next".
In this window you can select the amount of resources that the Pool will reserve from the Hosts to run its Guestsbutton on the right. You will see the New Pool form:
Enter a name for the Pool in the ID field, and an optional description. Select the priority of this pool from 1 (highest priority) to 5 (lowest). Then, activate the checkboxes of those hosts from where resources will be taken; in this case, you should have just one host. Finally, configure the resource reservation block:
- CPU reservation block size, in number of vCPUs.
- RAM reservation block size, in MB (although the slider shows RAM in GB to save space).
- The amount of "reservation blocks" that this Pool will reserve from the Hosts.
The resources that are assigned to a Pool, can be used by the Guests in that Pool and are not available to Guests in other Pools. Plan your Pools thoroughly and ahead of time, so that the platform will respond in the best way when a Host fails. As with Hosts, in order to avoid removing resources needed by running Guests, you can always increase the number of reservation blocks of a Pool, but you must disable it first to decrease it or to change the reservation block size.
Press the "Save" button when you have finished.
After saving the new Pool, it will appear in the tree view, while its information appears in the details view. The Pool Information form is very similar to the New Pool form, but the ID field is disabled, because it cannot be changed anymore. In general, for most objects of the platform, the Information form is similar to the New form, but with some fields disabled, for the properties that cannot be changed.
Besides the fields already described before, the Information form shows the current status of the Pool and its use of resources.
