[Vladislav Belogrudov <vladislav.belogrudov@xxxxxxxxxx>]

this bug still happens. Neutron openvswitch agent container tries to run
ip6tables-restore and fails because there is no ip6table_filter module
loaded. The module normally is loaded by the command itself. But inside
the container we don't provide /lib/modules ... With proper host mount
the error is gone.

  It seems iptables-1.4.21-16.el7.x86_64 does not support '-n' option
  used in the command above.
