[ovirt-users] ovirt and terraform disk size issue on template creation

Hi, I tried to create a VM from an OVF template imported on ovirt 4 but the VM has a disk size of 2 GBs and if I tried to attach a different disk this operation gone in timeout. I understand that you have to create the vm and assign disk and nic after the creation but I do not fully understand the templates attachments override option. Can you help me to understand the correct procedure to set the correct space on the new vm? Thanks, Marcello
