Title:
  nova-network should increase nf_conntrack_max

Status in OpenStack Compute (Nova):
  Opinion
Status in nova package in Ubuntu:
  Confirmed

Bug description:
  We ran into trouble when net.netfilter.nf_conntrack_count was
  exhausted by the system default of net.netfilter.nf_conntrack_max
  (65536).  As the typical use scenario for Nova can easily exhaust
  that, nova-network should probably set a more reasonable default, like
  2097152.

  Version: 2012.2.1+stable-20121212-a99a802e-0ubuntu1.4~cloud0 (from
  cloud-archive)
