Hi all,
I was able to create VMs using my Terraform code until I set the parameter destroy_cloud_config_vdi_after_boot to true.
Initially, it created a virtual machine and, after booting, removed the Cloud-Init disk as expected. However, from that point on, the VM started being created without a disk, even though tofu apply shows the following:
+ disk {
+ name_label = "carlo123-osdisk"
+ position = (known after apply)
+ size = 32212254720
+ sr_id = "589dad4d-2391-c2a9-589c-d34a9a7757ea"
+ vbd_id = (known after apply)
+ vdi_id = (known after apply)
}
tofu apply failes with:

When I commented out the cloud_config line the vm is created without a disk.
Xensource.log also shows the following :

I’m not sure where to start troubleshooting this, any help would be appreciated.
Thanks in advance,
