OK, I can definitely see how your professional experiences as described would lead to this amount of distrust. I work in data centres myself, so I have plenty of war stories of my own about some of the crap we’ve been forced to work with.
It’s not just the level of distrust, is the fact that we eventually moved all those nodes to LXD/Incus and the amount of random issues in day to day operations dropped to almost zero. LXD/Incus covers the same ground feature-wise (with a very few exceptions that frankly didn’t also work properly under Proxmox), is free, more auditable and performs better under the continuous high loads you expect on a datacenter.
When it performs that well on the extreme case, why not use for self-hosting as well? :)
I’m interested in have a play with LXD/Incus, but that’ll mean either finding a spare server to try it on, or unpicking a Proxmox node to do it.
Well you can always virtualize under a Proxmox node so you get familiar with it ahaha
