[Users] possible to attach cloud-init data to vm started from cd rom?
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.

Has nobody any clue regarding this? I also asked via IRC. I'm still testing and trying to get this working. Am 12.02.2014 13:37, schrieb Sven Kieske:

Okay, I think I found a bug: if you attach a cd-rom via run once and make it the primary boot device and you submit in the same step cloud-init data the xml file generated by ovirt looks like the following: both virtual cd roms get attached and show up in the xml the expected primary boot device shows up as: <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> with no entity (which it should have): <boot order='1'/> the cloud-init data shows up as the following: <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/var/run/vdsm/payload/934aebfd-7a7b-4c47-91be-97d58fb32b1e.34f0c17686175ad722c3b0a03f3db4d3.img' startupPolicy='optional'/> <target dev='hdd' bus='ide'/> <readonly/> <serial></serial> <boot order='1'/> the hdd gets "boot order='2'" this results in a wrong boot order: the vm trys to start from the cloud-init cd rom and fails and then boots the hdd. I will file a BZ for this. Tested with the following versions: rpm -qa vdsm vdsm-4.12.1-4.el6.x86_64 rpm -qa ovirt-engine ovirt-engine-3.3.2-1.el6.noarch Am 12.02.2014 13:37, schrieb Sven Kieske:

Here is the BZ, I also found 2 maybe related BZs which are already closed: https://bugzilla.redhat.com/show_bug.cgi?id=1064927 Am 12.02.2014 13:37, schrieb Sven Kieske:
