The xen-api-sdk project generates tools that let programmers control Xen virtualization servers from five popular programming languages: C, C#, Java, PowerShell, and Python. Xen is a platform for running and managing virtual machines, similar to VMware or VirtualBox but designed for enterprise data centers. The SDK translates Xen's management commands into natural, familiar functions in each target language, so developers can automate tasks like creating VMs, configuring storage, or monitoring server health without learning Xen's raw protocol. Rather than hand-writing separate toolkits for each language, this project uses a code generator built in OCaml. The generator reads Xen's API definitions and automatically produces ready-to-use source code for C, C#, Java, and PowerShell. Python is the exception, its module was written by hand and lives in a separate repository. Running the build produces source files that developers then compile and include in their own projects. Someone managing a Xen-based data center would use these SDKs to build custom automation scripts or management applications. For example, a Java developer could write a tool that provisions new virtual machines on demand, or a PowerShell user could automate routine server maintenance. The benefit is that each developer works in the language they already know, calling functions that feel native to that ecosystem rather than dealing with low-level API details. The project is notably built with an older version of OCaml (4.02.3), which means contributors need a specific, dated toolchain to work with the generation code. The maintainers, affiliated with Citrix, accept contributions through GitHub pull requests. The README doesn't go into detail about the API surface itself, it focuses on the build process for generating the SDK code rather than documenting what you can actually do with the finished toolkit.
