Depending on your machine type and using purpose, please pick up the corresponding tutorial to set up IPv6 access.
As you have access the subscription, you will find a KVM0-backend-url in your Connection Parameters. The number after KVM can be changed (eg., KVM1-backend-url, KVM2-backend-url,...) if you have multiple KVMs while the URL to your VPS via VNC is always displayed like the strings in the screenshot. Accessing KVM0-backend-url requires IPv6 address on your PC or your local network. Now you can click it and enter your VM immediately.
After click Connect, the user interface of your VM will be displayed in your browser. By default, Rapid.Space VPS provides a Debian installation guide, you can follow How to install default Linux VPS to install the Debian OS.
