SolusVM's development has become stagnant after OnApp acquired them - it seems as if OnApp doesn't want to develop SolusVM with features that compete with OnApp itself as they obviously are charging much higher rates.
Originally SolusVM's team was looking to expand features such as High Availability into the SVM2 update, and much other 'Cloud' Like features, but OnApp scratched that off after acquiring them.
At the moment SVM2 has been delayed constantly, and ETA's given by OnApp's team have been passed numerous times.
