Creating fedora linux cloud init template for proxmox manually
- Download fedora cloud image from https://alt.fedoraproject.org/cloud/. I used to download the last version in raw image
Creating VM in terminal
A VM creating process I ran in proxmox terminal using the following commands:
- Create a new VM. Here I defined a machine with internal Proxmox ID 403, with memory 4 GB, two cores and with two network interfaces. Name of the VM will fedora-cloud.
root@proxmox:~# qm create 403 --memory 4096 --cores 2 --name fedora-cloud --net0 virtio,bridge=vmbr0 --net1 virtio,bridge=vmbr1
- Here will the downloaded raw image will be imported to the VM as a hard drive and the image will be transfered to ocp1 storage
root@proxmox:~# qm importdisk 403 /var/tmp/Fedora-Cloud-Base-36-1.5.x86_64.raw ocp1
importing disk '/var/tmp/Fedora-Cloud-Base-36-1.5.x86_64.raw' to VM 403 ...

The uploaded image currently has a label unused, because it has not been attached to the the VM yet. And name of the image has been changed to vm-403-disk-0.raw. Let’s attach the image to the VM.
- Attaching an image to the VM. I use a default SCSI controller.
root@proxmox:~# qm set 403 --scsihw virtio-scsi-pci --scsi0 ocp1:403/vm-403-disk-0.raw
update VM 403: -scsi0 ocp1:403/vm-403-disk-0.raw -scsihw virtio-scsi-pci
- Add cloud-init drive
root@proxmox:~# qm set 403 --ide1 ocp1:cloudinit
update VM 403: -ide1 ocp1:cloudinit
Formatting '/mnt/pve/ocp1/images/403/vm-403-cloudinit.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off preallocation=metadata compression_type=zlib size=4194304 lazy_refcounts=off refcount_bits=16
root@proxmox:~#
- Make the cloudinit drive bootable and define in BIOS the boot starts from disk:
root@proxmox:~# qm set 403 --boot c --bootdisk scsi0
update VM 403: -boot c -bootdisk scsi0
root@proxmox:~#
- And finally set serial to enable a web VNC. Not relevant
root@proxmox:~# qm set 403 --serial0 socket --vga serial0
update VM 403: -serial0 socket -vga serial0
root@proxmox:~#
- Create a template from the VM
root@proxmox:~# qm template 403
root@proxmox:~#
Cloud-init configuration is able to define before creating a template or for any single VM that are being defined from the template.
- Clone a VM from the template:
root@proxmox:~# qm clone 403 103 --name test-vm --full
