Add Hyperconverged Hosts to Cluster

After deploying the self-hosted engine, you must add the remaining hyperconverged hosts to the virtualization cluster.

  1. Log in to the Administration Portal.
  2. Go to Compute and then click Hosts.
  3. On the Hosts pane, click New.

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

  4. From the Host Cluster drop-down list, select the data center and host cluster for the host.

    The Default data center is auto-selected.

    When you install Oracle Linux Virtualization Manager, a data center and cluster named Default is created. You can rename and configure this data center and cluster, or you can add new data centers and clusters, to meet your needs. See the Data Centers or Clusters tasks in the Oracle Linux Virtualization Manager: Administration Guide.

  5. In the Name field, enter a name for the host. This is the name you see in the UI.
  6. In the Hostname field, enter the fully-qualified domain name or IP address of the host.
  7. In the SSH Port field, change the standard SSH port 22 if the SSH server on the host uses a different port.
  8. Under Authentication, select the authentication method to use.

    Oracle recommends that you select SSH PublicKey authentication. If you select this option, copy the key displayed in the SSH PublicKey field to the /root/.ssh/authorized_keys file on the host.

    Otherwise, enter the root user's password to use password authentication.

  9. In the Power Management tab, check Enable Power Management and click + (plus) to configure an IPMI, iDRAC, ILO, or any other hardware management connection available.

    Note:

    You should configure the KVM host Power Management to allow the Engine application and system administrators to manage (reboot or power off) hosts in NonResponsive or NonOperational states when recovering from a host failure.

    In NonResponsive or NonOperational states, ssh management might not be able to recover the host forcing manual intervention. See Configure Power Management and Fencing for Host for more information.

  10. In the Hosted Engine tab, select Deploy from the Choose hosted engine deployment action dropdown.
  11. Click OK to configure the host as a virtualization node.
  12. Repeat this process for all remaining hyperconverged hosts.

    Important:

    Do not deploy the hosted engine on more than seven KVM hosts.
