![]() A notable exception is when problems occur during the unikernel's initialization (i.e., in connect functions), where unikernels will now fail hard as soon as they can. The module types provided by MirageOS 3 replace the previous error paradigm (a combination of exceptions and directly returning polymorphic variants) with one that uses the Result module included in OCaml 4.03 and up. ![]() The documentation generation system is still in beta, so please report issues upstream if you run across rendering issues or have other feedback. ![]() We hope you'll find the new organization more convenient. While documentation was previously available for most modules, it was scattershot and often required having several disconnected pages open simultaneously. Thanks to a lot of hard work, a fully interlinked set of module documentation is now automatically generated by odig and available for your reading pleasure at the MirageOS central documentation repository. The PRNG device-usage example in mirage-skeleton demonstrates some useful invocations of package. mirage will also consider version constraints for its own packages - from now on, opam should notice that releases of mirage are incompatible with your unikernel.įor more information on dealing with packages and dependencies, the documentation for the Functoria.package function will likely be of use. A user can now specify a version or range of versions for a package dependency, and the mirage front-end tool will construct a custom opam file including both those package dependencies and the ones automatically generated from mirage configure. MirageOS 3 has a much richer interface for dealing with the package manager and external library dependencies. You can also read how to run solo5 unikernels on FreeBSD via bhyve. Now you can mirage configure -t ukvm, build a unikernel, and run directly with the generated ukvm-bin! We've updated the "hello world" tutorial to reflect our excitement about ukvm - the ukvm target is considerably easier to interface with and configure than xen was, and for a lot of users this will be a clearer path toward operational deployment of unikernels.įor a lot more information on the Solo5 targets, see the earlier blog post announcing solo5, Unikernel Monitors: Extending Minimalism Outside of the Box, and the very readable solo5 repository README. MirageOS 3.0 is the first release that integrates the solo5 targets, virtio and ukvm, fully with the mirage front-end tool. Here's a summary of the things in MirageOS 3 that we're most excited about: Solo5 ![]() If you're interested in getting started with MirageOS 3 right away, you might be interested in the revamped guide to getting started, a small collection of example unikernels, or the porting guide for updating Mirage 2.x unikernels to Mirage 3. The system libraries themselves can be reused in traditional applications, just like any other software library.įull release notes are available on GitHub. MirageOS applications can be compiled to run as self-contained virtual machines (a few MB in size) on Xen or KVM hosts, FreeBSD's bhyve, or even as regular Unix processes (allowing access to regular debugging tools). We're excited to announce MirageOS 3.0! MirageOS is a modern, modular library operating system that allows the creation of small, secure, legacy-free services. ![]()
