What software will run on my vps?
Most of your VPS are run using Paravirtulization / FULL virtulization.
Hardware assisted virtualization, allowing for unmodified guests
Hardware assisted virtualization offers new instructions to support direct calls by a paravirtualized guest/driver into the hypervisor, typically used for I/O or other so-called hypercalls. It also provides additional execution modes: "root mode" and "non-root mode". Both of these modes have Rings 0-3; the host operates in root mode and has access to the real hardware, while the unmodified guest operates in Rings 0-3 of non-root mode and its "hardware" accesses are under complete control of the hypervisor.
This means that 99% of the programs which run on a normal windows / linux machine will run on our vps's with no problem.
