The CI-things can trigger OpenStack/XCP/Proxmox/Vmware and tell it to re-deploy your stuff. If you have many 'things', Nomad, Kubevirt (with ArgoCD or Flux), Tekton, Teletraan, Spinnaker are your best options in order of growing magnitude.

For me, if I were to run a small VMWare set for example, I would select Terraform as my orchestrator of choice. Then in my CI (GitLab-CI) I would make a step that once Packer has built a new VM image, I would update a file listing my to-be-deployed images and automatically commit it to a state repository. I would then also have Atlantis running which notices the change and runs terraform for me. It would add/remove all the resources needed for my VM to work with the correct network and storage. I would leave discovery and joining/leaving load balancers etc. to be the job of the VM image, perhaps via Cloud-init or Consul or something like that.

If I were to run a bit of a bigger setup, I might run Proxmox and Ceph, combine Kubevirt with that and run ArgoCD instead. Alternatively I might check out https://harvesterhci.io (via https://medium.com/@rmin.aminian/deploy-harvester-in-proxmox...).

  Discontinued Nomad is an easy-to-use, flexible, and performant workload orchestrator that can deploy a mix of microservice, batch, containerized, and non-containerized applications. Nomad is easy to operate and scale and has native Consul and Vault integrations. (by cneira)

Hey, afaik no, but you can compile nomad to work with OmniOS so i assume you can do the same for SmartOS. Haven't tried that in quite a while, so don't quote me on that. In this fork you can find fixes that add OmniOS support for older version of nomad.

But if you want to implement something like zones driver for smartos forking/updating this would be your best option:
