We (the NEC research labs teams that created ClickOS) are in the process of proposing a new unikernel subproject to the Xen community. Our aim is to provide a unikernel base (we call it Unicore) that consists of fine-granularity libraries, is highly configurable, and supports your unikernel project . Independent of whether you want to develop a new unikernel application or you want to port an existing application, we want to concentrate the required effort for maintaining and adding features (for instance hypervisor support) to this single OS base so that it is beneficial to almost all unikernel projects.
Please check out our proposal and send us your thoughts and comments via the xen-devel mailing list.
The subproject’s description can be found at:
