dhcp_agent.ini

dhcp agent 相关的配置信息。包括与 neutron 的同步状态的频率、超时、驱动信息等。

需要注意的是，这些 ini 文件内容多为注释掉的默认值的情况，是自动从代码中提取的。

  4. # iproute2 package that supports namespaces).
  5. # use_namespaces = True
  7. # The DHCP server can assist with providing metadata support on isolated
  8. # networks. Setting this value to True will cause the DHCP server to append
  9. # specific host routes to the DHCP request. The metadata service will only
  10. # be activated when the subnet does not contain any router port. The guest
  11. # instance must be configured to request host routes via DHCP (Option 121).

  14. # Allows for serving metadata requests coming from a dedicated metadata
  15. # access network whose cidr is 169.254.169.254/16 (or larger prefix), and
  16. # is connected to a Neutron router from which the VMs send metadata
  17. # request. In this case DHCP Option 121 will not be injected in VMs, as
  18. # they will be able to reach 169.254.169.254 through a router.
