Yeah I’m kind of amazed they don’t start out with explaining this. Usually there is at least a one-line explanation. From Wikipedia: “A unikernel is a specialised, single address space machine image constructed by using library operating systems. A developer selects, from a modular stack, the minimal set of libraries which correspond to the OS constructs required for their application to run. These libraries are then compiled with the application and configuration code to build sealed, fixed-purpose images (unikernels) which run directly on a hypervisor or hardware without an intervening OS such as Linux or Windows.”

> There has been a resurgence of research sys-tems exploring the idea of the libraryOS, ora unikernel,a model where target application is linked with a special-ized kernel and deployed directly on hardware, virtual orphysical Third paragraph > The unikernel is a cloud-era handle for the classic systemstechnique of linking an application with a library of oper-ating system components (including memory management,scheduler, network stack and device drivers) into a singleflat address space, creating standalone binary image that isbootable directly on (virtual) hardware [22]. The advantageof this approach is that kernel functionality can be special-ized to fit the needs of the target application to increasethe performance of the application or to support it within ahighly restricted execution domain.
