Here is some updates after I have done further investigation. Now I know that the problem terminates somewhere within ovirt-engine as the engine never passes a cdrom device to vdsm... I have an all-in-one ovirt setup installed on my system and am noticing some strange behavior when trying to create VMs with CDROMs. I have two different scenarios: Broken and Less Broken. I outline the user actions for both scenarios. In the Broken scenario, it seems impossible for a cdrom device to be created for the vm in the engine db. For the less broken scenario I can get a device to appear in the db, but it won't be plugged into the vm without manually updating a field in the db. I am hoping someone can help me to shed some light on this problem. Thanks!

In order to get it to be added to the VM I had to: engine=# update vm_device set is_plugged='t' where device_id=<dev_id>; When looking at the engine.log the only suspicious entries are: 2012-03-28 16:23:02,458 WARN [org.ovirt.engine.core.compat.backendcompat.PropertyInfo] (http--0.0.0.0-8080-5) Unable to get value of property: managedDeviceMap for class org.ovirt.engine.core.common.businessentities.VmStatic 2012-03-28 16:23:02,459 WARN [org.ovirt.engine.core.compat.backendcompat.PropertyInfo] (http--0.0.0.0-8080-5) Unable to get value of property: managedDeviceMap for class org.ovirt.engine.core.common.businessentities.VmStatic Note that this installation is from source. I used ./create_db_devel.sh to make the DB but did not run engine-setup. I am wondering if this is a configuration issue or an actual bug. Any ideas?

Hello,
I am currently experimenting with an all-in-one setup (engine and vdsm on same host). I have my storage configured (data/iso/export domains all attached) and my local host is Up. When I try to create a VM with a CDROM device the VM starts but has no CD device at all. Any ideas why this would be happening?
not sure if related, but same area: https://bugzilla.redhat.com/show_bug.cgi?id=800253
well, it sounds the same, but, i'm a bit concern due to the fact CD-ROM configuration entry is missing from your vmCreate command, whereas in my bug, vmCreate should hold CD-ROM entry, but libvirt omits that configuration as it claims the source is not accessible (its their bug). just to make sure, please attach the following:
- vdsm log - libvirtd.log (/var/log/libvirtd.log) - guest log (/var/log/libvirt/qemu/<vmName>.log

I am not seeing anything here to indicate why the cdrom is being omitted. Confused.
