Interesting, but this raises a couple of questions:
- isn't OpenNebula in some way also an abstraction layer for the
hypervisors, so in a sense a libvirt driver for OpenNebula
is a bit 'redundant' ? Maybe i didn't understood well the
principles behind OpenNebula :-) (sorry first time I learn about
this).
- what is the future of that patch ? Basically libvirt internals
changes extremely fast, so unless a driver gets included as part
of libvirt own code source, there is a lot of maintainance and
usability problems resulting from the split. Do you intent to
submit it for inclusion, or is that more a trial to gauge interest ?
Submitting the driver for inclusion means the code will have to be
reviewed, released under LGPL, and a voluteer should be available
for future maintainance and integration issues.
thanks !
