Can anyone weigh in on whether any of these can be used for a cluster?
I use VMware in my homelab via vMUG, and I’m sure that’s going to get destroyed next, so I’m looking for an alternative that can allow for running VMs across hosts using shared storage with migrations between hosts. I’d prefer FOSS, but the only hypervisor I know supports all of this right now is hyper-V. I really REALLY don’t want to use hyper-v… Most of my workloads are Linux, with a handful of Windows servers that I use for an internal domain and testing.
Maybe OpenStack or OpenNebula?
Any suggestions?
Why wouldn’t you use Proxmox?
I have not observed anyone using it in a cluster.
From the brief Google searching I’ve done it appears to be possible, though, I’m not sure if proxmox skills will help me professionally. I used VMware before because I needed to learn VMware esxi and vcenter. I know it fairly well at this point.
I want to target a hypervisor solution used in large companies, I’m not sure that’s proxmox. Currently I’m leaning towards OpenStack, since I know some cloud providers use it for VPS offerings. I know enough about hyper-V that I know I don’t want to use it, ever. At least outside the context of Azure VMs. I can’t really do Azure cloud at home (they’re is a way, I’ve looked into it, but it’s very expensive), though my current workplace uses Azure extensively.
I’m just not aware of any company using proxmox as a VM platform, whether single host or clustered.
Well I can’t speak for enterprise but for me it works pretty well in a 3 node cluster. I can live transfer VMs that are hosting services with very little interruption. Proxmox also supports HA and Ceph but I haven’t used those features.
Good to know. I’ll examine everything carefully. I’ve been debating on replacing my existing monolithic iSCSI storage configuration with Ceph, so maybe that will weigh in… Having something that can access Ceph natively is a big plus. Otherwise I need something to sit in between that can basically translate Ceph to iSCSI luns, which is just more complexity that I’d like to avoid.
A lot of things to consider. Thank you for the comments.
The list for those that don’t want to read the whole article:
- Proxmox
- XCP-ng
- OpenNebula
- SUSE Harvester
- Oracle VM VirtualBox
I like Virtualbox, use it myself in several instances but I would never consider it a replacement for VMware.

Now what about EUC replacements. That’s the more sticky situation.
For those who don’t know, EUC stands for end user computing.
Why is so hard to setup VMs for employees? Maybe I’m missing something but it seems like a matter of just creating a virtual machine with a GPU attached.
Very significantly different performance requirements. The client communication needs tuning for fast UI response. Unified comms (zoom, teams, etc) need to be redirected to avoid bottlenecking through the server. usage patterns aren’t very well distributed (everyone logs in at 8) which means you can’t over subscribe as much.
It’s very different than a server workload.
