The overrides are applied only to initial device configuration passed to QEMU
via the commandline. Later hotplug operations will not apply any modifications.
+The properties of a device can be queried directly in qemu (e.g. for the
+``virtio-blk-pci`` device) via ::
+
+ # qemu-system-x86_64 -device virtio-blk-pci,?

Configuring override for a device alias which is not used or attempting to
remove a device property which is not formatted by libvirt will cause failure
to startup the VM.
