@olivierlambert Aha, thanks

I have some VM templates with large (tens of GB) disks attached.

Creating a VM from these templates used to be near-instant as XO would do a fast (copy-on-write) clone of the template disks.

Recently it seems XO has started doing a full copy of the template's disks when creating a VM. VM creation from these templates now takes several minutes and I see long-running VM.copy and Async.VDI.copy tasks in the task list whilst this is happening.

Was there a deliberate change to making VM creation do a full copy rather than a fast clone?

Thanks.
