I have a server with a bunch of services just as Docker containers. I see that Proxmox is popular among the self-hosting community. I was wondering why?

I understand that running things in a VM provides better security than running them in a container. But is the difference so important given the relatively low risk that an exploit happens inside a container that leads to doing damage to the host machine?

There’s also obviously the additional overhead of using Proxmox. It wouldn’t be an issue for me as I should have enough resources to, say replace all my Docker containers with VMs. I’m more wondering if the security difference is so massive, or if there is another reason I’m missing why people use Proxmox.

Or am I misunderstanding how people use Proxmox? I was assuming people would use it like how you use Docker, i.e. different services get their own VM/container. If you have a different kind of setup I’d be interested in hearing it.
