# 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.

# ebtables is inherently racey. If you run it by two or more processes
# simultaneously it will collide, badly, in the kernel and produce
# failures or corruption of ebtables. The only way around it is for
# all tools running ebtables to only ever do so with the --concurrent
# flag. This requires libvirt >= 1.2.11.

# If you don't have this then the following work around will replace
# ebtables with a wrapper script so that it is safe to run without
