Ragnarok Online Private Server installation, while possible to be run on our VPS, is not included in the Basic Management support that we provide. Additionally it's also something that we do not cover through our Hourly Management Plan. You may however contact some contributors on our Facebook Page to help you out on the installation, it's guaranteed but it's something you can try aside from searching from the internet.
On the other hand, you may also try to install an eAthena Raganarok Server to your VPS if you have a fair knowledge on various Linux SSH commands. You may find the listed websites below helpful throughout the installation process (NOTE: these tutorials might be outdated).
