Clusters

Oracle Linux Virtualization Manager creates a default cluster in the default data center during installation. You can configure the default cluster, or set up new appropriately named clusters.

Creating a New Cluster

  1. Go to Compute and then select Clusters.

    The Clusters pane opens.

  2. Select New.

    The New Cluster dialog box opens with the General tab selected on the sidebar.

  3. From the Data Center dropdown list, select the Data Center to associate with the cluster.
  4. For the Name field, enter an appropriate name for the data center.
  5. For the Description field, enter an appropriate description for the cluster.
  6. From the Management Network dropdown list, select the network for which to assign the management network role.
  7. From the CPU Architecture and CPU Type dropdown lists, select the CPU processor family and minimum CPU processor that match the hosts that are to be added to the cluster.

    For both Intel and AMD CPU types, the listed CPU models are in logical order from the oldest to the newest. If the cluster includes hosts with different CPU models, select the oldest CPU model from the list to ensure that all hosts can operate in the cluster.

  8. From the Compatibility Version dropdown list, select the compatibility version of the cluster.

    Note:

    For more information on compatibility versions, see Changing Data Center and Cluster Compatibility Versions After Upgrading.

  9. From the Switch Type dropdown list, select the type of switch to be used for the cluster.

    By default, Linux Bridge is selected from the dropdown list.

  10. From the Firewall Type dropdown list, select the firewall type for hosts in the cluster.

    The firewall types available are either iptables or firewalld. By default, the firewalld option is selected from the drop-down list.

  11. The Enable Virt Service checkbox is selected by default. This checkbox specifies that the cluster is to be populated with virtual machine hosts.
  12. (Optional) Review the other tabs to further configure the cluster:
    1. Select the Optimization tab on the sidebar to select the memory page sharing threshold for the cluster, and optionally enable CPU thread handling and memory ballooning on the hosts in the cluster. See Deployment Optimization.
    2. Select the Migration Policy tab on the sidebar menu to define the virtual machine migration policy for the cluster.
    3. Select the Scheduling Policy tab on the sidebar to optionally configure a scheduling policy, configure scheduler optimization settings, enable trusted service for hosts in the cluster, enable HA Reservation, and add a custom serial number policy.
    4. Select the Fencing policy tab on the sidebar to enable or disable fencing in the cluster, and select fencing options.
    5. Select the MAC Address Pool tab on the sidebar to specify a MAC address pool other than the default pool for the cluster.
  13. Select OK to create the data center.

    The cluster is added to the virtualization environment and the Cluster - Guide Me menu opens to guide you through the entities that are required to be configured for the cluster to operate.

    You can postpone the configuration of these entities by selecting the Configure Later button. You can resume the configuration of these entities by selecting the respective cluster and selecting More Actions and then choosing Guide Me from the dropdown menu.
