Cleanly restart the default libvirt network
# Yury V. Zaytsev <> (C) 2011
# This work is herewith placed in public domain.
# Use this script to cleanly restart the default libvirt network after its
# definition have been changed (e.g. added new static MAC+IP mappings) in order
# for the changes to take effect. Restarting the network alone, however, causes
# the guests to lose connectivity with the host until their network interfaces
