I am going to redo my server from scratch. I installed virt-manager hoping to build it in there and keep setup guide/notes for myself for when i move it to the server pc.
Im not fluent in linux speak so bare with me.
Does anyone know how I can reach the proxmox IP when its in a vm set up with virt-manager? I installed it with the default network adapter setting and it gave me 10.0.2.15 for the ip. I couldnt reach it from the main system or a debian vm. I deleted both the proxmox and debian vm’s and will try again. Should I be using a different network mode in virt-manager? is it even possible to do what im trying to do?
I want to try out using proxmox with a debian vm instead of baremetal omv for docker. I was also thinking about using a VM of omv for my storage drives.
anyone have input on this stuff? I saw docker has a desktop app that seems pretty good so I was going to try that. Or would it be better to just install debian without a DE and use docker from the command line?
should i just use debian for the drive shares too? should i stick with smb?
does it even make sense for me to use proxmox? I figured it would be easier for me (personally) to keep things backed up. I like the idea of being able to create new vm’s to experiment with without breaking my main/only server.
Thanks

Unfortunately Proxmox doesn’t use libvirtd, so Virt-Manager doesn’t interact with it. It’s designed entirely around using the web interface.
Your options here are to either stick with Proxmox without Virt-Manager, or use straight KVM. If you want a web interface for KVM, there’s Cockpit, which is pretty decent for most basic tasks, but definitely a little lacking in advanced features, so you’ll end up going to Virt-Manager for stuff like modifying virtual hardware. I think you can also use OpenStack as a web interface, but I’ve never played around with it myself.
Honestly, if you’re a little newer to Linux I would probably stick with Proxmox, as it’s a very well designed purpose built hypervisor.
For Docker, you’ll want to deploy a VM and then setup Docker within the VM. Never run Docker from your hypervisor, it likes to fuck with IPtables in ways that break VM networking.
Seems like you’re nesting virtualization too much. Stick with 1 level of virtualization. If it’s a server, I’d use proxmox on bare metal. Its a server so split services per VM/container. Install OMV on its own VM. Another for docker, with docker services ran by a non root user.
Install the proxmox iso directly on the hardware. Then setup a Debian without DE in a vm to run docker. Use Portainer to manage Docker containers.
Storage can then be assigned via Proxmox to the vm’s that need it.
Excellent suggestion, although I would look at using Dockge instead of Portainer these days. It’s very new and a little more feature limited, but it does a much better job of actually explaining how and why things are failing. If you’re new at Docker then Portainer is a nightmare because all it does is scream “WRONG” and then storm off if you so much as put a single typo.
Perfect description of my experiences with portainer. I didn’t know about dockge and it looks very promising! Thanks
This is what I do, but with alma instead of debian.
Proxmox can run containers directly, but I haven’t tried it yet.
Pretty sure Proxmox only supports LXC containers, not OCI
You could install docker with proxmox, it’s just debian after all, then you could install portainer to visualize them. I just don’t think it’s a good practice to install docker directly on a hypervisor, too much risk to screw something up and then you may need to reinstall everything affecting all other VMs.
You could however install docker on a lxc. Not the easiest approach but less risky.
Edit: or Dockge in your case
