| nfs.srv.world +----------+----------+ node01.srv.world |
| | | |
+-----------------------+ +-----------------------+
|
| [1] | Install some packages on a new Node. |
|
[root@node01 ~]#
[root@node01 ~]# dnf -y install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm [root@node01 ~]# dnf -y install qemu-kvm libvirt virt-install vdsm cockpit systemctl enable --now libvirtd cockpit.socket |

Input information of Node you'd like to add.
For authentication method, it selects SSH key-pair on this example.Required items are Hostname or IP address of target Node and authentication method (password or SSH key-pair). Select [SSH Public Key], then SSH Public Key contents are displayed on the right box, copy all text and paste to [/root/.ssh/authorized_keys] on target new Node, then it's possible to use SSH key-pair authentication. |
|
| [5] | Configure [Power Management]. This feature enables on hardwares which has IPMI. So if your Machine corresponds, configure, or if not, Click [OK] to proceed without configuring it. |
|
| [6] | After adding a new Compute Node, required tasks are run, so [Status] turns to [Installing]. |
|
| [7] | After successfully finishing configuration tasks, [Status] turns to [Up], That's OK to add a new Compute Node. |
