15 # CA-23900: Warning: when VIFs are added to windows guests with PV drivers the backend vif device is registered,
16 # unregistered and then registered again. This causes the udev event to fire twice and this script runs twice.
17 # Since the first invocation of the script races with the device unregistration, spurious errors are possible
18 # which will be logged but are safe to ignore since the second script invocation should complete the operation.
19 # Note that each script invocation is run synchronously from udev and so the scripts don't race with each other.
21 # Keep other-config/ keys in sync with device.ml:vif_udev_keys
