4.8 HVM Instances do not Boot with CDROMs on Oracle VM Server

Hardware virtualized (HVM) instances created with a CDROM fail to boot on Oracle VM Server. Paravirtualized (PV), and hardware virtualized with paravirtualized drivers (PVHVM) instances are not affected, and boot with the CDROM.

Workaround: Set the hw_cdrom_bus=xen property on the image, for example:

$ glance image-update --property hw_cdrom_bus=xen image_id
