To me it seems like:

• you want to do a lot of stuff yourself on arch
• but there’s quite some complicated stuff to learn and try

I’d try Proxmox VE and, if you’re also searching for a Backup Server, Proxmox Backup Server.

I recommend these because:

• Proxmox VE is a Hypervisor, you can just spin up Arch Linux VMs for every task you need
• Proxmox VE, as well as Proxmox BS are open source
• you can buy a license for “stable updates” (you get the same updates, but delayed, to fix problems before they get to you)
• includes snapshots, re-rolls, full-backups, a firewall (which you can turn on or off for every VM), …

I personally run a Proxmox VE + Proxmox BS setup in 3 companies + my own homelab.

It’s not magic, Proxmox VE is literally Debian 13 + qemu + kvm with a nice webui. So you know the tech is proven, it’s just now you also get an easy to use interface instead of virsh console commands or virt-manager.

I personally like a stable infrastructure to test and run my important and experimental tuff upon. That’s why I’m going with this instead of managing even the hypervisor myself with Arch.
