Has anybody heard about Virualizor? A powerful web based control panel for VPS and mainly it supports openVZ, Xen PV, Xen HVM, and Linux KVM virtualization. In addition, it is a softaculous group product.
The best thing, which I've been noticed is their pricing. It is very low as compared to other panels, but Virtualizor is pretty new(perhaps only for me). Anyway, as it is a softaculous product so I believe it will gain popularity very soon. Overall, these kind of new innovation helps to make a healthy competition in the market.
