[ovirt-users] boot from cdrom & error code 0005

Hi. I have created a new storage domain (data domain, storage type nfs) to use it to upload iso images. I have so uploaded a new iso and then attach the iso to a new vm. But when I try to boot the vm I obtain this error: booting from dvd/cd... boot failed: could not read from cdrom (code 0005) no bootable device The iso file has been uploaded with success in the data storage domain and so the vm lets my attach the iso to the vm in the boot settings. Can you help me? Thank you
