# This is a terrible, terrible, truly terrible work around for
|
|
# environments that have libvirt < 1.2.11. ebtables requires that you
|
|
# specifically tell it you would like to not race and get punched in
|
|
# the face when 2 run at the same time with a --concurrent flag.
|
|
#
|
|
# INSTALL instructions
|
|
#
|
|
# * Copy /sbin/ebtables to /sbin/ebtables.real
|
|
# * Copy the ebtables.workaround script to /sbin/ebtables
|
|
#
|
|
# Note: upgrades to ebtables will overwrite this work around. If you
|
|
# are packaging this file consider putting a trigger in place so that
|
|
# the workaround is replaced after ebtables upgrade.
|
|
#
|
|
# Additional Note: this file can be removed from nova once our libvirt
|
|
# minimum is >= 1.2.11.
