4.3. Creating and Deleting Hardware Pools

Creating and deleting Hardware Pools is a simple task using oVirt's Administration User Interface.

4.3.1. Creating Hardware Pools

Creating a hardware pool in which the virtual machines can run in an optimal fashion is crucial for system performance. For example, the hardware administrator might need to create a VM Resource Pool out of 5 physical nodes and a set of iSCSI targets. The resource pool would contain a combined total of 10 processors, 20GB RAM, 100GB storage. The hardware administrator then assigns 3 users to this resource pool and assigns constraints on those users, for example; Each user may use 3 VCPUs, 30GB storage and 6GB RAM. However, the first step is to create the Hardware Pools.

To do this you need to know the following:

  • The number of hosts required

  • The number of processors required

  • The amount of storage required

  • The amount of RAM required

  • The permissions and privileges of the users

To create a hardware resource pool from the Navigator Panel

  1. Use the Navigator panel to select the required hardware pool node. The Summary page and the Hardware Pool menu displays.

  2. The Navigator toolbar appears at the bottom on the panel.

    Click Add Hardware Pool. The Add Hardware Pool dialog box displays.

  3. Enter the name of the new resource pool and click the Create Hardware Pool button. A message indicates that the hardware pool was successfully created. Click OK.

    Note:

    You must enter a name for the new hardware pool. oVirt validates the name field and prompts you to enter a name before the resource pool is created.

  4. You can now add hosts, storage, virtual machines and users to the new hardware pool. Click the appropriate option on the menubar. Adding hosts, storage and virtual machines is described later in this section.

Hardware Pool Names
Names can be any combination of alphanumeric characters, spaces and special characters. Valid name lengths are 1-256 characters. It is recommended that you use meaningful names for the resource pools.
