Unikernels and Explorations
summary
Claims that Linux can be converted into a usable unikernel and that hypervisor and toolchain changes are needed to make that practical, with prototypes running on QEMU/Xen and OSv/IncludeOS-style images. Work focuses on converted Linux to single-address-space unikernel, snapshot / instant VM cloning to cut startup latency, and low-level fixes like VDSO adjustments and interrupt-stack (IST) handling on x86. A lightweight manager, remote logging and a small DFS prototype exist; performance gains are case-dependent and compatibility with multiprocess apps remains unresolved.
