I have a trusty UnRaid server that has been running great for almost 3 years now, with some kinks and headaches here and there, but mostly very stable. Now I'm entertaining the idea of setting that box up with ProxMox, and running UnRaid virtualized. The reason being that I want to use UnRaid exclusively as a NAS and then run all dockers and VMs on ProxMox (at least that's how I'm picturing it). I would like to know your opinion on this idea. All I have is Nextcloud, Immich, Vaultwarden, Jellyfin, Calibre, Kavita and a Windows VM I use to update some hardware every now and then. I mainly want to do that for the backup capabilities in ProxMox for each instance. Storage is not a concern, and I have 64GB of ECC Ram running in that box. What are the Pros and Cons, or is it even worth it to move all this to ProxMox?
Proxmox doesn't run docker containers. You can probably install docker to make it run them, but it's not supported.
I also wouldn't run unraid on a virtual disk just to provide storage. Personally, I have one almalinux VM running on Proxmox that runs all my containers and has a big virtual disk to store my media.
Proxmox is Debian at its core, which is supported by Docker. There’s no good reason to not run Docker on the bare metal in a homelab. I’d be curious to know what statement Proxmox has made about supporting Docker. I’ve found nothing.

Second result for "docker on proxmox".
That’s not a definitive support statement about Docker being unsupported. In fact, even in the Admin Guide, it only provides recommendations. The comment I replied said Docker is unsupported by Proxmox. I maintain that there is no such statement from Proxmox.
Maybe not explicitly unsupported, but I think "it interferes with some mechanisms on which we rely" should be more discouraging than a policy statement.
