Do you provide a control panel (ISP Manager, cPanel, DirectAdmin, etc.) or is there a bare OS?
A clean operating system distribution is installed on the VDS, or you can choose an option with a pre-installed control panel.
In our control panel, you can reinstall the OS on VDS, reboot it, control the load on the server, use VNC.
Also in https://cp.vdsina.com you can park domains.
