Installation takes time and needs Linux knowledge 2. The missing GUI management 3. And the inability to run unmodified guests like Windows on an OpenVZ host I also had other wishes like integrated backup and restore, live-migration, central configuration management and integrated virtual appliances download. So I presented this last year to our development team – a few months later, we proudly presents the first release of our *Proxmox Virtual Environment<http://pve.proxmox.com/> .* Now we have the virtualization platform for the enterprise, licensed under GNU GPLv2. Proxmox VE is the *only *virtualization platform which can do all of the following on one physical host: - Container Virtualization (OpenVZ) - Full virtualization (KVM) - Para-virtualization (KVM) We encourage everybody to test Proxmox VE and give feedback, for download and documentation please visit the *Proxmox VE Wiki </>.* Feel free to get in contact with me directly - martin at proxmox.com. -------------- next part -------------- An HTML attachment was scrubbed...
