Hi,
You are probably creating the VM as a dependent on the template (thin VM),
it means that the VM's disk should be created on the same storage domain as
the template disk.
In order to create the VM with a disk on a different storage domain, you
can either create the VM as an independent (clone) or copy the template
disk to the storage domain you want to create the VM disk on.

No, you should be able to create cloned disks on a storage domain that is
different from the one(s) the template image(s) is on.
How did you try to do that?
If you tried to create thin-provisioned disks as Eyal mentioned above via
the API, the operation should fail with an error of
TEMPLATE_IMAGE_NOT_EXIST (it shouldn't be possible to select a storage
domain that doesn't hold the template image via the webadmin)
If you specified that the disks should be cloned to a different storage
domain correctly then the engine.log should reveal what is the problem.
