OSv (stylized OSv) is a cloud computing focused[1] computer operating system released on September 16, 2013. It is a special-purpose operating system built to run as a guest on top of a virtual machine, thus it does not include drivers for bare-metal hardware. It is a slim, bare bones unikernel including just the functionality necessary to run Java or POSIX applications.[2] For this reason, it does not support a notion of users (it's not a multiuser system) or processes - everything runs in the kernel address space.[3] Using a single address space removes some of the time-consuming operations associated with context switching.[4] It uses large amounts of code from the FreeBSD operating system, in particular the network stack and the ZFS file system. OSv can be managed using a REST Management API and an optional command line interface written in Lua.
