If this title is appropriate, we can shorten it for the sidebar.

@rrajendran17 I restructured some parts to make the procedures flow better.

Approving now so we can merge and close the related issue. Note that I found some issues (capitalization, punctuation, markup, etc.) but I prefer to create my own PR for such cleanup work.

Thank you for the document update! I have a few nits below.
|
|
||
| For VMs provisioned as downstream cluster nodes, ensure external connectivity is available by enabling DHCP and configuring dns_server=8.8.8.8 and natOutgoing=true on the subnet. This allows the VMs to obtain a default route and perform DNS resolution. | ||
|
|
||
| Since VMs attached to Kube-OVN overlay networks use private IP addresses, a route to the VM subnet must be configured on the rancher VM via the external IP used for SNAT/DNAT. This enables SSH access to the VM nodes from the Rancher UI. |

This line is a bit confusing. Do we need a route to the VM subnet installed on the Rancher VM, or have DNAT/SNAT configured for the VM subnet? Or both?

A route is required for the private subnet with EIP (configured in the vpc nat gw) as nexthop.
I have rephrased the wording for better understanding in the latest commit.
