What control panel do you want to use? Plesk can easily install Magento too via the Application Vault which comes with the Plesk Powerpack for just $2/mo. Directadmin would require a manual install which we could try to assist with per request.
The Virtuozzo Powerpanel isn't a control panel so that's not possible. The Virtuozzo Powerpanel is used for rebooting your VPS and monitoring resource usage of your VPS. You need a control panel to get Magento up and running by us. Magento requires certain versions of PHP, etc which all come installed with a control panel. With no control panel you'd need to install and configure everything via the command line so we wouldn't recommend that unless you have extensive knowledge at that. Hope this helps.
