Hi all. I was curious about some of the pros and cons of using Proxmox in a home lab set up. It seems like in most home lab setups it’s overkill. But I feel like there may be something I’m missing. Let’s say I run my home lab on two or three different SBCs. Main server is an x86 i5 machine with 16gigs memory and the others are arm devices with 8 gigs memory. Ample space on all. Wouldn’t Proxmox be overkill here and eat up more system resources than just running base Ubuntu, Debian or other server distro on them all and either running the services needed from binary or docker? Seems like the extra memory needed to run the Proxmox software and then the containers would just kill available memory or CPU availability. Am I wrong in thinking that Proxmox is better suited for when you have a machine with 32gigs or more of memory and some sort of base line powerful cpu?
Proxmox is available free. You pay for support and maybe other things with a license, but you can download it and give it a spin at no cost. I just switched to Proxmox around 1m ago when I restarted my homelab project after years on hiatus. I used to use Esxi before Broadcom bought VMware and decided to suck. I like it so far.
It might be overkill for your needs. I’m running it because I want to play with setting up and managing Win Server (I only have experience managing existing servers on Win), so there’s a distinct reason for me to be on Proxmox even though I’m a Mac and Linux person. I agree that it might be overkill for your i5 if you only plan to run one Ubuntu instance on it. However, a lot of homelabbing is about having an environment to try out and learn new skills. If that’s something that’s interesting to you, it might be worthwhile.
Keep in mind that you could also run KVM for virtualization if you find reason for VMs. You’re not limited to Proxmox. And if you see no need for VMs, you already have three devices to do the things you bought them to do.
For stability you want the enterprise subscription which is not free but is fairly reasonable
