I am currently developing a piece of software that will act as an all purpose control panel for a specific niche. I have coded the vast majority of the control panel already, and want to purchase a cheap (under $25/mo) VPS to test the installation and performance of the control panel.
As a result of me testing various configurations the main feature I am looking for is free (or very cheap) OS reloads.
I want to be working under a CentOS environment, and have a decent amount of CPU that I can use. Disk space and bandwidth are really not an issue, as I am simply testing using this VPS to test the software I am developing.
Are you looking for a specific virtualization software such as: xen, openvz, parallels, etc? If you choose a provider with a good control panel, OS reloads should not be very difficult. Are you looking for a managed or unmanaged solution?
