In order to run hvt unikernels, you need a custom "tender" named
solo5-hvt on the host system instead of qemu (qemu uses virtio,
solo5-hvt a custom device setup). The binary is built when you compile
solo5 (i.e. download / clone https://github.com/solo5/solo5).

You can start your unikernel with something like `solo5-hvt
--net:service=tapX -- network.hvt --ipv4=10.0.0.2/24`.

If you're not in control of the host system, or would like to use an
intermediate layer / orchestration system, please don't hesitate to
provide further details, and let us discuss a possible solution.

Best,
