You have created a new data center and a new cluster within it, now you need to populate the cluster with the Red Hat Enterprise Linux hosts you installed in Section 1, “Install Red Hat Enterprise Linux Hosts”. Before they can be used, they have to be manually attached to the Red Hat Enterprise Virtualization platform. Perform the following procedure for each host you have installed.
Note that this step is required for Red Hat Enterprise Linux hosts only, if you are using Red Hat Enterprise Virtualization Hypervisors for this lab you only have to approve the hosts with a click, as you did in Section 4, “Approve the Red Hat Enterprise Virtualization Hypervisor”. This time, attach the hosts to your newly created cluster.
To attach Red Hat Enterprise Linux hosts
You should still be on the New Data Center - Guide Me dialog. If you are not, select your newly created data center and click Guide Me. On the dialog, click Configure Host.
The New Host dialog displays.
Figure 63. Attach a Red Hat Enterprise Linux Host
Configure the following options:
The Data Center and Host Cluster are already pre-selected.
Enter the Name and the IP Address or resolvable hostname of the host. Enter the Root Password used to log in to the host.
Click OK. On the Tree pane, click Expand All and select the Danube host. It displays on the Hosts tab with a status of "Installing". The installation may take a few minutes as the required packages are being downloaded. Once installation is complete, the status will update to Reboot and then Awaiting.
When the host is ready for use, its status changes to Up.
