cloud init

Hey folks. So I made myself a custom cloud-init file, because the UI cloud-init is limited. Actually, each time I create a VM I run a script to customize a final cloud-init file (so each VM can be different). I save the file to /var/lib/vz/snippets/ubuntu-homelab-cloud-init.yml. (so far I am...

I created an Ubuntu 24 CloudInit template and deployed multiple VMs from it. Everything is working fine, except for one issue: SSH with password authentication. I tried editing the sshd_config file to allow password-based login by making the following changes: Set PasswordAuthentication yes...

Hi all, I am trying to deploy a VM with a custom QCOW2 image in Proxmox and want to use a custom cloud-init user-data file to provision it. I have created my custom user-data file and uploaded it under the local:snippets storage as userdata.yaml. Then I applied it to the VM using the command...

Greetings, I've been fighting with cloud-init with templates on Proxmox for the last few hours, and I want to capture what I've learned, and maybe be told where I'm doing it wrong, or taking the hard way. First off, a few specific things that I've learned. Proxmox has it's own cloud-init...

Just wanted to share my (successful) procedure for creating in PVE9 a VM Template for a Debian Trixie Server with Cloud-Init, which I have done in the past for previous Debian versions in PVE8. This is most useful to quickly spin up a Debian server for any purpose. The following procedure was...

Dear all, I am trying to clone my VM template while setting up a static ip. As I am using Ansible, I try to use the community.general.proxmox_kvm module. However, I do not get the VM to have a static ip. For the template I use a Debian 12 (bookworm) template using Learn Linux Tv's guide. Below...

When importing an Ubuntu cloudimage VM from VMware I noticed that the networkinterface name has changed, and potentially happens again in the future. So I want to make it static inside the VM. Context is that the VM originally is configured by VMWare's Cloud-init approach (...

I am using the proxmox api to clone a template. When I create a custom user snippet with all the same information from the cloud init file when created from the gui and adding to it, customization commands. proxmox no longer makes the host name the same as the vm name. Is there a way to bring...

I want to configure the MTU of VMs with cloud-init, but there is no Web GUI to apply MTU value into automatically generated configs. I don't want to manage custom config files myself for that. Please let us configure cloud-init MTU value with Web GUI.

I have been working on my process of spinning up new templates/instances from cloud images for various distros. All is going good so far. Where I am struggling is with the --cicustom switch when applying to a VM instance, it appears I am not able to seed the user-data and the network config...

I see countless Youtube videos online that when they refer to cloud-init with proxmox they assume that you will be creating a template and inside that template you are going to attach a configdrive2 disk with the dynamic cloud init data that proxmox provides because the native Linux...

Hello all, I'm in the process of adopting Ubuntu 24 as the next upgrade in my infra but on validation it looks like cloud-init doesn't work anymore. My host: root@proxmox-server:~# pveversion pve-manager/8.1.4/ec5affc9e41f1d79 (running kernel: 6.5.11-8-pve) Later edit: Turns out that...
