[ovirt-users] 3.6 vm from template with cloud-init. Not able to confirm OK button

Hello, I have created a template based on a CentOS 7.1 VM where I installed cloud-init. Now I'm trying to create a VM from that template using cloud-init and changing hostname and network parameters. It seems that in "Initial Run" section there is something wrong because if I press OK it doesn't happen anything but a sort of dotted square around the ok button, but I'm not able to see what is the thing that is not ok and correct it..... Can I debug anywhere? BTW: if I succeed in this preliminar test I would like to create a vm pool from this same template where, for every started VM in the pool (stateless is ok for them), a new hostname and a preconfigured static ip is set (I have not and I can't set up a dhcp server on that network). Is something configurable in vm pool with cloud init? Thanks Gianluca
