Integration of existing VMs into UEC

Most companies have running virtualization stacks like VMWare, Xen or something KVM-based like proxmoxVE. It would be helpful to be able to easily integrate existing virtual machines into UEC, because it´s unlikely that a company will build a second virtualization system.

It should be possible to take over existing virtual machines to UEC via scripts or - even better - via the UEC web interface.

This will boost the number of UEC installations and will help to spread cloud computing in general.
