Cloud images inherently come with one NIC. Once you create you cloud init image below create it in ProxMox as a machine, not a template and run it. This multi-nic image works for other providers as well. You will want to install netplugd to make this work.

sudo apt-get install netplug


sudo mv netplug /etc/netplug/netplug

sudo chmod +/etc/netplug/netplug

Spin up the machine and add an extra network port in Proxmox and test it if you want. Otherwise you can turn it into a template.

Cloud init images are great for ProxMox Templates and for launching machines via Terraform. 

This code is also available here:

Ubuntu images are available here:


You need to install libguestfstools to customize the image.

sudo apt update -y && sudo apt install libguestfs-tools -y

 Once the tools are installed you can start customizing your image:

sudo virt-customize -a focal-server-cloudimg-amd64.img --install qemu-guest-agent
sudo virt-customize -a focal-server-cloudimg-amd64.img --run-command 'useradd pmatra'
sudo virt-customize -a focal-server-cloudimg-amd64.img --run-command 'mkdir -p /home/pmatra/.ssh'
sudo virt-customize -a focal-server-cloudimg-amd64.img --ssh-inject pmatra:file:/home/pmatra/.ssh/authorized_keys
sudo virt-customize -a focal-server-cloudimg-amd64.img --run-command 'chown -R pmatra:pmatra /home/pmatra'
sudo virt-customize -a focal-server-cloudimg-amd64.img --root-password password:PASSWORD
sudo virt-customize -a focal-server-cloudimg-amd64.img --run-command 'echo /etc/sudoers >> pmatra ALL=(ALL) NOPASSWD:ALL'

After all of that is done if you want to load it into Proxmox as a template, you need to upload it to your Proxmox Server and run this code.

qm create 9000 --name "ubuntu20-cloudinit-template" --memory 2048 --cores 2 --net0 virtio,bridge=vmbr0
qm importdisk 9000 focal-server-cloudimg-amd64.img local-lvm
qm set 9000 --scsihw virtio-scsi-pci --scsi0 local-lvm:vm-9000-disk-0
qm set 9000 --boot c --bootdisk scsi0
qm set 9000 --ide2 local-lvm:cloudinit
qm set 9000 --serial0 socket --vga serial0
qm set 9000 --agent enabled=1
qm template 9000

If you want to clone the image manually you can do it this way via ProxMox Shell or SSH

sudo qm clone 9000 999 --name test-clone-cloud-init sudo qm set 999 --ipconfig0 ip=,gw= sudo qm start 999

I did an Ansible Kubernetes deployment to 4 ProxMox hosts successfully after using my Terraform K8 plan. I use WSL Ubuntu on Windows to do the deployment. I actually used WSL through MobaXTerm which makes things a lot easier with a built in SFTP. Ansible also install the Kubernetes Dashboard for you. The instructions are in the in Gitlab. 

I added Terraform to my Proxmox setup using Telmate. I can now launch multiple VMs in a few minutes. I took cloud images and injected SSH keys, root passwords, Qemu Guest Agent software. The Terraform plans are here- I created the cloud init images from some help off the web but I had to customize it. I will put the code up in the blog to show how to make it.

Also added this script to launch Kubernetes servers, nodes, and storage
