Is there a way to add other disks when instantiating a VM template? Something similar as the network cards ?
The only way we found is to start the VM on HOLD, then start it and quickly add others disk. My bonus question is why can’t we add disks when the VM is on HOLD ?
Yes but you should use CLI instead of sunstone (GUI).
One way to perform this is the next:
$ onetemplate instantiate [template ID] --disk [disk name]
