how to create a "linked clone" in ESXi 6
Posted on 2016-07-19
I have a hypervisor that I install on my local laptop named "Oracle vBox". In this tool, I am able to create a VM, then create a "linked clone" from the original VM. When I do this the base VM for windows will be about 12GB, but the linked clone will be only 1GB. This is great for saving space.
We have the need to do the same thing in our ESXi 6 development environment. We need to spin up a few windows 10 desktops but they don't need to have amazing performance. It would be great if we could keep them small so the backups go quick.
What I did was create a VM named windows_10_base with a 100GB [c] drive thin provisioned. Then I cloned this to a template, then I created a new VM from the template. Maybe I am reading this wrong however when I browse the VM templates folder and look at my template there is column named "provisioned space" and the provisioned space reads 100GB.
I am not sure if that is actually the disk space the template is consuming, but I was hoping for a small footprint using thin provisioning and linked clones.
Did I go about this the correct way in ESXi? Is there a way I can do the same thing as the Oracle vBox "linked clone"?
