Choosing an hypervisor (lemmy.world)

Hello everyone! During one of those illuminated evenings, I got the idea to move my small server in Scaleway to some more powerful server in Hetzner. If I will make the move, I am thinking of splitting the server in various VMs, to host different services that belongs to different trust boundaries, for example:

  • A Lemmy/writefreely instance
  • Vaultwarden/Gitea
  • Wireguard tunnel to my home infrastructure
  • Blogs, and other convenience services

In order to achieve the best level of separation, I was thinking of using VMs. My default choice would be Proxmox, because I used it in the past, and because I generally trust it, however I am trying to evaluate multiple options, and maybe someone has good or better experiences to share.

Other options I thought about are:

  • Run everything in Docker. I am going to do this nevertheless, but Docker escapes are always possible, especially with public facing images that I did not write myself and/or that require a host volume.
  • KVM directly? I am OK even without a GUI to be honest. I am not aware if there is some ansible module or even better Terraform provider for this, it would be great. (EDIT: I found https://registry.terraform.io/providers/dmacvicar/libvirt/0.7.1 which seems awesome!)
  • ESxi? I have no experience with this solution.

Any idea or recommendation?

In the places where I've had to make similar decisions, I've used the need for 'advanced' features to make the call. If I'm looking for storage or networking redundancy, or I've been interested in running multiple hosts systems, or I've been looking to play with overlay networks, then I'll grab Ovirt, Proxmox, VSphere, or Openstack (depending). When I just want something simple-ish, I just KVM / Podman on a Linux machine.

Good point, I don't have any advanced use case, except maybe some slightly more complex network setup. Probably this is achievable with KVM too (and/or some firewall-fu). I would like to have fully IaC, so I don't have to click through guis, so the availability of Terraform providers might be a dealbreaker (which I didn't look yet for Proxmox, for example).
