keepalived goes into restart and segfault loop

[Steven Dake]

keepalived will go into a restart loop if ip_vs isn't loaded.

See this thread:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=619415

Apparently ip_vs needs to be loaded by the keepalive init scripts, or in our case, probably the bootstrapping code.

    Load ip_vs module for keepalived

    If ip_vs is not loaded keepalived will enter a restart loop. To fix that
    load ip_vs module every time we start the container.
