Proxmox VPS server

[VGT Hosting]

I would like to begin a discussions about people opinions regarding Proxmox VE technology which allows to create virtual private servers using openVZ (for para visualized server) and KVM (for fully visualization). We were very successful to setup few windows, linux, frebsd virtuall private servers on one single quad core box. Has anybody tried Proxmox for commercial use or had any experience with this Virtual Environment?

Thanks
