With free esxi over, not shocking bit sad, I am now about to move away from a virtualisation platform i’ve used for a quarter of a century.
Never having really tried the alternatives, is there anything that looks and feels like esxi out there?
I don’t have anything exceptional I host, I don’t need production quality for myself but in all seriousness what we run at home end up at work at some point so there’s that aspect too.
Thanks for your input!
- KVM/QEMU/Libvirt/virt-manager on a Debian 12 for minimal installation that allows you to choose backup tools and the like on your own.
- Proxmox for a mature KVM-based virtualizer with built in tools for backups, clustering, etcetera. Also supports LXC. https://github.com/proxmox
- Incus for LXC/KVM virtualization - younger solution than Proxmox and more focused on LXC. https://github.com/lxc/incus

This is my go-to setup.
I try to stick with libvirt/virsh when I don’t need any graphical interface (integrates beautifully with ansible [1]), or when I don’t need clustering/HA (libvirt does support “clustering” at least in some capability, you can live migrate VMs between hosts, manage remote hypervisors from virsh/virt-manager, etc). On development/lab desktops I bolt virt-manager on top so I have the exact same setup as my production setup, with a nice added GUI. I heard that cockpit could be used as a web interface but have never tried it.
Proxmox on more complex setups (I try to manage it using ansible/the API as much as possible, but the web UI is a nice touch for one-shot operations).
Re incus: I don’t know for sure yet. I have an old LXD setup at work that I’d like to migrate to something else, but I figured that since both libvirt and proxmox support management of LXC containers, I might as well consolidate and use one of these instead.
I use cockpit and my phone to start my virtual fedora, which has pcie passthrough on gpu and a usb controller.

We use cockpit at work. It’s OK, but it definitely feels limited compared to Proxmox or Xen Orchestra.
Red Hat’s focus is really on Openstack, but that’s more of a cloud virtualization platform, so not all that well suited for home use. It’s a shame because I really like Cockpit as a platform. It just needs a little love in terms of things like the graphical console and editing virtual machine resources.
Ooh, didn’t know libvirt supported clusters and live migrations…
I’ve just setup Proxmox, but as it’s Debian based and I run Arch everywhere else, then maybe I could try that… thanks!
In my experience and for my mostly basic needs, major differences between libvirt and proxmox:
- The “clustering” in libvirt is very limited (no HA, automatic fencing, ceph inegration, etc. at least out-of-the box), I basically use it to 1. admin multiple libvirt hypervisors from a single libvirt/virt-manager instance 2. migrate VMs between instances (they need to be using shared storage for disks, etc), but it covers 90% of my use cases.
- On proxmox hosts I let proxmox manage the firewall, on libvirt hosts I manage it through firewalld like any other server (+ libvirt/qemu hooks for port forwarding).
- On proxmox I use the built-in template feature to provision new VMs from a template, on libvirt I do a mix of
virt-cloneandvirt-sysprep. - On libvirt I use
virt-installand a Debian preseed.cfg to provision new templates, on proxmox I do it… well… manually. But both support cloud-init based provisioning so I might standardize to that in the future (and ditch templates)
Did you read? I specifically said it didn’t, at least not out-of-the-box.
Re incus: I don’t know for sure yet. I have an old LXD setup at work that I’d like to migrate to something else, but I figured that since both libvirt and proxmox support management of LXC containers, I might as well consolidate and use one of these instead.
Maybe you should consider consolidating into Incus. You’re already running on LXC containers why keep using and dragging all the Proxmox bloat and potential issues when you can use LXD/Incus made by the same people who made LXC that is WAY faster, stable, more integrated and free?
Hey look, it’s the Incus guy. Every time this topic comes up, you chime in and roast Proxmox and it potential issues with a link go a previous comment roasting Proxmox and it’s potential issues and at no point go into what those potential issues are outside of the broad catch all term of ‘bloat’.
I respect your data center experience, but I wish you were more forward with your issues instead of broad, generalized terms.
As someone with much less enterprise experience, but small business it administration experience, how does Incus replace ESXi for virtual machines coming from the understanding that “containerization is the new hotness but doesn’t work for me” angle?
The migration is bound to happen in the next few months, and I can’t recommend moving to incus yet since it’s not in stable/LTS repositories for Debian/Ubuntu, and I really don’t want to encourage adding third-party repositories to the mix - they are already widespread in the setup I inherited (new gig), and part of a major clusterfuck that is upgrade management (or the lack of). I really want to standardize on official distro repositories. On the other hand the current LXD packages are provided by snap (…) so that would still be an improvement, I guess.
Management is already sold to the idea of Proxmox (not by me), so I think I’ll take the path of least resistance. I’ve had mostly good experiences with it in the past, even if I found their custom kernels a bit strange to start with… do you have any links/info about the way in which Proxmox kernels/packages differ from Debian stable? I’d still like to put a word of caution about that.
They’re obviously looking for a type 1 hypervisor like Esxi. A type 2 hypervisor like virtualbox does not fit the bill.
VB is awful.
And I use it every day.
It’s like a first-try at a hypervisor. Terrible UI, with machine config scattered around. Some stuff can only be done on the command line after you search the web for how to do it (like basic stuff, say run headless by default). Enigmatic error messages.
Proxmox works well for me
proxmox
If you’re running mostly Linux vms proxmix us really good. It’s based on kvm and has a really nice feature set.
I’ve used Hyper-V and in fact moved away from ESXi long ago. VMWare had amazing features but we could not justify the ever-increasing costs. Hyper-V can do just about anything VMWare can do if you know Powershell.
