I am not sure what exactly you are asking. Are you looking for a control panel in general? Or are you looking for a control panel to run inside of freevsd?
If you are just looking for a control panel, be advised that freevsd is not exactly a control panel; it is just a software virtualization software that allows you to create virtual server.
If you are looking for control panel to run inside freevsd, you should know that freevsd comes with a control panel of its own. As for other control panels, you will have to experiement to see if it works well, because of the limitation of freevsd.
On a side note, the developer of freevsd also sells a Windows-based control panel that allow you to control the creation and management of virtual servers.
Thanks Peter, really appreciate the response. I was actually looking for a control panel (eg Plesk, CPanel etc) when I came across FreeVSD - I saw that there were a collection of PHP scripts to help manage it and thought it looked interesting. That's why I was wondering if anyone out there was using it and how good it was
