Daniel Erez has submitted this change and it was merged. Change subject: core: set address explicitly for VirtIO-SCSI devices ...................................................................... core: set address explicitly for VirtIO-SCSI devices Upon VM start, libvirt uses automatic address allocation for defining addresses for each device (when not defined addresses explicitly). As part of the automatic allocation, libvirt limits maximum units (disks) for each controller [6 (narrow bus) / 15 (wide bus)]. In order to bypass this limitation, engine should set each device address explicitly while keeping unit value (disk's index in VirtIO-SCSI controller) unique and consecutive in the VM devices.
