On this example, add [node01.srv.world] to existing oVirt Cluster like follows.

+-----------------------+          |          +-----------------------+
|   [   Admin Node   ]  |10.0.0.30 | 10.0.0.25| [    oVirt Engine   ] |
|    dlp.srv.world      +----------+----------+     ctrl.srv.world    |
|                       |          |          |                       |

+-----------------------+          |          +-----------------------+
| [   Shared Storage  ] |10.0.0.35 | 10.0.0.51|  [   oVirt Node    ]  |
|     nfs.srv.world     +----------+----------+   node01.srv.world    |
|                       |                     |                       |
+-----------------------+                     +-----------------------+

[1]	Install some packages on a new Node.

[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

[root@node01 ~]#

systemctl enable --now libvirtd cockpit.socket

[2]	Access to oVirt Admin Portal, and Click [Compute] - [Hosts] on the left pane.

[3]	Click [New] button on the top of right pane.

[4]

Input information of Node you'd like to add.
Required items are Hostname or IP address of target Node and authentication method (password or SSH key-pair).

For authentication method, it selects SSH key-pair on this example.
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 function 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.
