Re: [ovirt-users] VM Deployment By Template
Hi,
just to correct this, this is wrong:

When you create your VM based on the template check in advanced
options
– Resource allocation and see if the option there for template
provisioning
is set to clone or to thin provision. Clone in your case I believe
would create
a 40GB image file based on the template whereas thin provision will
create
you a thin provisioned disk just using the same actual
data amount as the thin provisioned template.
If you have a "thin" template and create a new vm using the option:
"clone" what ovirt does is copy the thin template to a new disk.
when you use "thin" ovirt does not create a new disk for the vm, instead
the new vm shares the thin disk with the template (same file!)
and creates another file just for the differences between template
and vm, which accumulate over time.
notice that you can not delete a template which has thin provisioned
vms depending on it unless you delete all those vms.
