PVE API for cloud-init drive

[yuri1987]

hey guys, I'm working on extending current salt cloud module to support cloud-init (for qemu new vm's/clones)

from a first look, looks quite simple, just add ide[n] config with the following for example:
"ide0" : "local:101/vm-101-cloudinit.qcow2,media=cdrom" (this varies based on the next available id for VM)
and this is indeed working, also I can populate the cloud-init args such as IP and DNS...

my problem is that I can't start the VM after creation, I'm getting the following error:
TASK ERROR: volume 'local:101/vm-101-cloudinit.qcow2' does not exist

I've tried changing to raw instead of qcow2 or adding size argument, nothing helps
the only solution I found is to go to the cloud-init section in gui and press regenerate image, I've tried to inspect what it does, and I saw it sends a put request to the /config endpoint, my current problem is that i don't know exactly what to send to this endpoint so it will regenerate the cloud-init image

any suggestions?

Hi dietmar, thank you for your fast response, it seems that I have tried to overcomplicate it, as the qm example says, it is sufficient just to pass the storage name + :cloudinit, without specifying vmid or image file type in this way:
local:cloudinit
local-lvm:cloudinit

I was able to proceed with my use case
