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!

Has nobody any clue regarding this?
I also asked via IRC. I'm still testing
and trying to get this working.

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
