MirageOS unikernels run directly on Xen, e.g. http://roscidus.com/blog/blog/2016/01/01/a-unikernel-firewal...

> I replace the [QubesOS] Linux firewall VM with a MirageOS unikernel. The resulting VM uses safe (bounds-checked, type-checked) OCaml code to process network traffic, uses less than a tenth of the memory of the default FirewallVM, boots several times faster, and should be much simpler to audit or extend.

NanoVMs has OSS tools for golang unikernels on multiple hypervisors and cloud platforms, https://nanovms.com/dev/tutorials/running-go-unikernels

Nanos runs not just go but pretty much any language you want to throw at it:
