Speaking for myself, that's exactly why I work at Joyent. I believe in OS virtualisation (whether you call them zones or containers) for multi-tenancy, in high quality tools for debugging both live (DTrace) and post mortem (mdb), and in open source infrastructure software (SmartOS, SDC, etc). I also believe that as an industry and a field, we should continue to build on the investments we've already made over many decades. The Unikernel seems, to me at least, to be throwing out almost everything; not just undesirable properties, but also the hard-won improvements in system design that have fired so long in the twin kilns of engineering and operations.
