So, I run OPNsense in a VM on Proxmox. There is only one drawback I am aware of, which is when I update the Proxmox host itself, I’ll need to attach a monitor/keyboard/mouse to it. Theoretically, if the upgrade was fully automatic and never needing any intervention or user input, it’d be possible without: But the reality is more that it might need user input, but the OPNsense VM will not be booted i.e. network will be down i.e. I need direct access to the Proxmox host.

You didn’t say how you currently keep your data…
