Hi All
Im very stumped on how to create VMs from templates I've made, but
having them installed with their own disks.
Please can some one guide me on how to do this?
I have Ovirt running, with local storage hypervisors.
Anytime I try to use a template, the vm is created and booted with the
template's disk.
I would especially appreciate how to do this with ansible.
Im trying to automate CentOS and Ubuntu VMs.

When you make a VM from a template there are two possibilities.
If the VM type is set to desktop, a qcow overlay is created against the
template's disk images. Any changes made in the VM are stored in the
overlay..
If the VM type is set to server the template's disks are copied to a new
disk, it will have the same name as the template disk, but it is in fact
a new disk with the template data copied over.
