Introducing OSv: A New Open Source Operating System for the Cloud
summary
OSv is a from‑scratch guest OS that runs one application in a single address space (no user/kernel crossings), targets JVM workloads so you can drop a JAR and run, and uses huge pages, ZFS, C++ kernel code and a tiny set of paravirtual drivers for KVM/Xen/Amazon AMIs. It avoids fork/exec, cuts context‑switch and boot latency, exposes tracepoints and a ballooning prototype, and already runs Cassandra and memcached with measurable performance and manageability gains.
