Fedora VM - no luck with cloud init...

[RafalSkolasinski]

Hi,

I am trying to prep myself some VM templated based on cloud init.
I checked https://www.apalrd.net/posts/2023/pve_cloud/ and had success creating Ubuntu template manually.

Then I managed to use a script similar to the one from the blog to create a series of templates for Ubuntu & Debian systems.

But when I try to do it for Fedora I hit quite some issues... There is no network inside the created VM.
They don't get any IP, and cannot reach anything.
Also when logging I see

Failed to connect to bus: Connection refused

and calling nmcli also gives an error

$ nmcli device
Error: Could not create NMClient object: Could not connect: Connection refused.

Here is the script I used

#!/bin/bash

# May need to install "libguestfs-tools " on proxmox host

function download_image() {
    mkdir -p images
    wget -nc -P images $1
}

#Create template
#args:
# 1: vm_id
# 2: vm_name
# 3: file name in the current directory
function create_template() {
    if [[ "$force_recreate" != "true" ]] && qm status $1 &>/dev/null; then
        echo "Template $2 ($1) exists, skipping..."
        return
    fi
    echo "Deleting existing template $1"
    qm destroy $1

    echo "Creating template $2 ($1)"
    qm create $1 --name $2 --ostype l26

    echo "Customizing image $3"
    virt-customize -a $3 --install qemu-guest-agent
    virt-customize -a $3 --install avahi

    #Set boot device & add cloud init disk
    qm set $1 --scsi0 ${storage}:0,import-from="$(pwd)/$3",discard=on
    qm set $1 --boot order=scsi0 --scsihw virtio-scsi-single
    qm set $1 --agent enabled=1,fstrim_cloned_disks=1
    qm set $1 --ide2 ${storage}:cloudinit

    #Set networking to default bridge
    qm set $1 --net0 virtio,bridge=vmbr0
    qm set $1 --memory 4096 --cores 4 --cpu host

    # qm set $1 --serial0 socket --vga default
    qm set $1 --ipconfig0 "ip6=auto,ip=dhcp"

    qm set $1 --ciuser ${username}
    qm set $1 --sshkeys ${ssh_keyfile}

    # Resize disk and finalize template
    qm disk resize $1 scsi0 ${disk_size}
    qm template $1
}

# Global Config

# export force_recreate=true

I figured it out - customizing image with

virt-customize -a $3 --install qemu-guest-agent
virt-customize -a $3 --install avahi

was messing everything out, removing these lines fixed it.

Also added

qm set $1 --serial0 socket --vga serial0
qm set $1 --ciupgrade 0

to avoid some segfaults with agetty and lengthy upgrade after first boot (I prefer to do it myself).
