Hey,
I have created a template that the disk is a thick (raw) with a size of 15GB.
I am trying to create a VM from that template but having the disk with a much larger size, both template and the VM are set to use thick and I create the new VM with the clone option, so there’s no link between the new VM and the template.
So far the only solution I managed to find is to adjust the size after creating the VM.
This looks like reasonable flow. You create the vm from a template, so you inherit the disk size from the template. Then you modify the disk to the required size.
For example, this situation causes a problematic step when using Foreman/Satelite as trying to provision a VM based on a template but with different size for the OS disk.
Why is this problematic?
I assume that one of the ways to solve it is to convert the template somehow into an “image”? like using OpenStack Glance as a place to store “templates” as images? Any other way besides using Glance?
If you always need to resize the template, why not create another templated with the right size based on this template? Nir
