Re: [libvirt] [PATCH RFC] Remove the Open Nebula driver

The Open Nebula driver has been unmaintained since it was first

It also has a major design flaw, in that it only knows about guests
that it has created itself, which makes it of very limited use.

Discussions wrt evolution of the VMWare ESX driver, concluded that
it should limit itself to single-node ESX operation and not try to
manage the multi-node architecture of VirtualCenter. Open Nebula
is a cluster like Virtual Center, not a single node system, so
reasoning applies.

The DeltaCloud project includes an Open Nebula driver and is a much
better fit architecturally, since it is explicitly targetting the
distributed multihost cluster scenario.

Thus this patch deletes the libvirt Open Nebula driver with the
recommendation that people use DeltaCloud for managing it instead.

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.
