You may use whatever hosting control panel you wish to install. You will have to install it yourself unless you wish to use our paid services to install it for you. Some of these control panels can be installed within your VPS Control Panel. Here's a few free and paid ones. This is not a complete list. You can search for others on the net:
CWP (CentOS Web Panel for CentOS Only - free): http://centos-webpanel.com/
WHM (Web Hosting Manager - paid): https://cpanel.com
Webuzo (paid): https://www.webuzo.com/
If there is a problem with our servers due to an install we have provided,we will reinstall for free. Otherwise, if you install a control panel yourself you will need to contact the support services for the panel you are using.
