Hi,

I've imported a number of VMs that I previously was running under a
self-hosted libvirt configuration. Most of the VMs at the source did not
have a cdrom device (but some did) because I just added one as I needed to.

Now that the VMs have been imported into oVirt, none of them have a
cdrom device. Even booting with the "Attach CD" option doesn't create a
cdrom device. I can't see any way to get oVirt to re-create the missing
device.

Is there a way for me to add these missing devices to my VMs?

Unfortunately there is no supported way of doing that. In oVirt, we add a cd-rom device for every VM during its creation and don't enable to add or remove a cd-rom. If no cd-rom device is added by default during import from libvirt then that's a bug, could you please file a bug on that (https://bugzilla.redhat.com) ?

However, you can resolve it in a hacky way by modifying the database directly:

insert into vm_device (device_id, vm_id, type, device, is_managed, is_plugged, is_readonly, address) values (uuid_generate_v1(), (select vm_guid from vm_static where vm_name='your-vm-name'), 'disk', 'cdrom', 't', 't', 't', '');

I'm running oVirt 4.1 on CentOS 7.3.1611 with a hosted engine setup. VMs
were migrated from a Debian Stretch machine running libvirt 3.0.0 with
qemu 2.8.0.

Thanks,
Chris
