Prior to this update, starting multiple para-virtualized guests in quick succession could cause several instances of a hot plug script to compete for the same lock file. Consequently, the connection may have timed out with the following error message written to standard error:
Error: Device [id] (vbd) could not be connected. Hotplug scripts not working.
This update applies a patch that corrects the locking mechanism, so that such timeouts no longer occur.
