This option is currently listed in:

http://docs.openstack.org/trunk/config-reference/content
/section_networking-options-reference.html

however, the help text isn't very good:

dhcp_agents_per_network = 1     (IntOpt) Number of DHCP agents scheduled
to host a network.


To fix this bug, I think we need two patches
1. a patch to neutron to fix the help text to better explain why/when you would alter this option
2. ensure the new networking guide provides detailed information in the agent configuration area

Title:
  Add details on dhcp_agents_per_network option for DHCP agent HA

Status in OpenStack Neutron (virtual network service):
  New
Status in OpenStack Manuals:
  Triaged

Bug description:
  The current documentation does not specify any information about the
  "dhcp_agents_per_network" configuration option in
  /etc/neutron/neutron.conf. Using this option, it is possible to have
  the scheduler automatically assign multiple DHCP agents to a tenant
  network, which provides high availability.

  If that option is not set, you have to manually assign multiple DHCP
  agents to each network, which does not scale in terms of management.

  Would it be possible to document this option here?
