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?
I am with you on the advantages of running it in a VM. The isolation a VM provides is really nice. Snapshots FTW.
LXCs let you get all the benifits of VMs with fewer drawbacks, I recommend that approach if you want some extra sandboxing than docker on bare metal provides.
