Change subject: backend: Filter orphaned Host Devieces on refresh ...................................................................... backend: Filter orphaned Host Devieces on refresh In some hotplug scenarios (especially those related to SCSI devices) it can happen that libvirt reports to VDSM an internally inconsistent list of devices, namely that the parent_device points to a device not in the list or is empty altogether. Those cases violate the DB constraint imposed on the host_device and cause the RefreshHostDevicesCommand transaction to fail. Since those cases are impossible to handle at lower layers and we need to maintain consistend view of the host devices for our main business logic, we now ignore those invalid devices in the hostdev refresh cycle.
