This repository contains some unikernel developed/maintained by Tarides. They are usually buildable with:
$ mirage configure -t <your-target>
$ make depends
$ mirage build
Their deployements depend on your target. Usually, we prefer to deploy unikernels on KVM but Xen is another possible target for these unikernels.
Specially about the SMTP stack (which includes all of these unikernels), a deployer exists with a tutorial to explain how to deploy our SMTP stack from scratch with KVM: ptt-deployer
