This is a quick review of proxmox.

Comming from and rejecting the Broadcom acquisition of VMware… I had very high hopes for Proxmox. In the end it was a serious disappointment and I requested a refund. Here is a list of my complaints:

• ceph crashed and I could not recover the installation. The cluster had to be rebuilt.
• PVE (Proxmox) seems to be biased toward LXC and not VMs
• In my prefered configuration my VMs and containers are to be considered immutable and state changes are to be held on a shared drive. The idea is that the VM is repaced and connected to the state drive. It just does not work well here.
• LXC registry is limited
• LXC migration does not work without shutdown
• ALL the documentation and google results are very old
• I posted on the community support and had not received a reply in 48hours
• could not find anything to support confiuration as code
• when I created a user account PVE did not create a user folder in the home folder and I could not login with that account
• I’m not sure what it was but when I looked at /proc/version inside a CT(container) they were all the same regardless of the OS.

PS looks like Ubuntu has contracted LXC/LXD as of 5/1/2024. Unfortunately the docs are old and microcloud is buggy.

REF:

docker, podman, rkt, runc, others - are best suited for micro services even though that can deploy OS containers but then you have hidden costs

k0s, k3s, k8s, rancher, others…

LXC/LXD - are best suited for OS as nested layers or qemu.

UPDATE

I requested and received a refund for my 3 proxmox licenses. So I started installing ubuntu 24.04 onto those machines only the installer kept crashing. I do not know for certain, however, everything including my intuition tells me that there is a problem induced but the proxmox partition. Which seems strange because it’s Debian. Oh well.
