*Perhaps you could be interested in this project:
I discovered three major issues in the usage scenarios of OpenVZ in the
1. 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
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
Now we have the virtualization platform for the enterprise, licensed under
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 </>.*
