Is there a web based Virtual Machine Manager which is available from Ubuntu repositories. I am looking for some thing which can would be useful for be web hosting companies.These web hosting companies can buy server space on one place and they can sell this server space to one customer who would use this Virtual Machine etc to host website etc inside a cloud. The Virtual Machines could be Windows Servers,Solaris servers,Some Linux servers etc or stuff like that. I hope I make myself clear. Let me know if some one has an idea for the same. I am aware of libvirt but that is not web based thing.
