Pretty clever to boot a virtual QEMU VM and pass through the physical disks for installation. Nice that it can be done without a support request.
Any issues or recommendations considering the Proxmox route? You do port forwarding or multiple ipv4?
Thanks for putting this idea in my head!
I also have an instance of PFSense running and any VMs that don't need a full IP address to themselves can just be port forwarded through the firewall.
I know you can do this with iptables but I am too lazy to learn how it works.
