Getting Started

Why a whole new OS is required

Today’s cloud-based applications run a heavyweight stack: the hypervisor, which divides the hardware resources among virtual machines; the operating system, which divides the virtual machine’s resources among applications; and the application server, which divides the application’s resources among the end users.

Rapid VM builds - Capstan

Capstan is a tool for rapidly building and running your application on OSv. Capstan is as simple and fast as using Docker for creating containers, but the result is a complete virtual machine image that will run on any hypervisor with OSv support. A typical Capstan image is only 6-7MB larger than your application itself, and adds about 3 seconds to the build time.

If you haven’t made your application available as a “virtual appliance” because of the complexity of doing it on a conventional OS, Capstan could be just what you need. From fast horizontal scaling to demo and evaluation images, virtual appliance delivery of your application is now fast thanks to the low overhead of Capstan.

OSv Kernel and MPM Files

The recommended way to run OSv locally is using Capstan

In order to build OSv image you need to download corresponding OSv kernel and Capstan packages (aka MPM files). These artifacts can be found at particular OSv release assets section.
