Hi, I would like to know if the following scenario is supported in ovirt (currently testing 3.3.2). You have a vm with an attached disk. You want to start this vm with an attached iso image via cd-rom you want to pass to this started system cloud-init metadata via "run once" or REST. I know that ovirt passes the metadata by creating an ISO and attaching this ISO to the VM as an CD-ROM itself. My tests so far included the following: 1. shut down the vm 2. click run once 3. switch boot order to boot from cd-rom, attach an ISO 4. activate cloud-init metadata and pass some data over it actual result: the system boots from hard disk, not from the attached iso. Second test: 1. shut down the vm 2. edit the vm, change boot order to boot from cd-rom, attach iso 2. click run once 4. activate cloud-init metadata and pass some data over it actual result: the system boots from hard disk, not from the attached iso. Is this not possible or am I doing it wrong? Any hints would be appreciated! -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
