Given your arguments, I'm okay with the idea, but like Laine pointed out, it might be wise to get feedback from the opennebula guys first (commit b811851 shows that Abel Míguez Rodríguez was the original contributor in May 2009, now in cc).

I knew nothing about Open Nebula, so I went searching. I noticed the following on its about page: *"User Interfaces*: Unix-like command line and libvirt interface for the management of the cloud infrastructure" (http://opennebula.org/documentation:features) Since they're claiming the libvirt driver as a feature, they will probably have something to say about this removal. At the very least they'll want to point to the DeltaCloud driver instead of libvirt.
