Install on Proxmox VE

Import the gate42 disk into a new VM with two network bridges.

These steps use the Proxmox VE 8 command line on the node. The same settings work in the web interface. You need two bridges: one towards the internet for the WAN (usually vmbr0), and one for the LAN, for example vmbr1.

1. Create the VM and import the disk

Copy the image to the node, then:

qm create 4200 --name gate42 --memory 4096 --cores 2 --cpu host --ostype other \
  --net0 virtio,bridge=vmbr0 --net1 virtio,bridge=vmbr1 \
  --scsihw virtio-scsi-single --serial0 socket --agent enabled=1
qm disk import 4200 gate42-1.8.2-b17-amd64.qcow2 local-lvm
qm set 4200 --scsi0 local-lvm:vm-4200-disk-0 --boot order=scsi0
qm disk resize 4200 scsi0 20G

On Proxmox VE 7, use qm importdisk instead of qm disk import. Use your own storage instead of local-lvm. net0 is NIC 1, the WAN; net1 is NIC 2, the LAN.

The default firmware (SeaBIOS) is fine. For UEFI, choose OVMF without pre-enrolled keys, since gate42 does not boot with Secure Boot.

2. Start it

qm start 4200

Open the console (noVNC or the serial console, xterm.js). After one to two minutes it shows the root password (first boot). Log in at https://<WAN address>:8443, or https://192.168.1.1:8443 from a machine on vmbr1 (first login).

Notes

gate42's DHCP server answers on the LAN. If vmbr1 already has a DHCP server, turn one of them off.
The QEMU guest agent is installed, so Proxmox shows gate42's addresses and can shut it down cleanly.
