OpenStack 虚拟机无法获取IP

[Cena_2008]

我新搭建的一套基于L版本OpenStack，网络模式是Nova-Network，虚拟机创建之后无法自动获取IP，但是在数据库查看已经把IP分配给这个虚拟机了
虚拟机启动日志如下
==============================================================================

查看nova服务都正常，dnsmasq也正常启动着，不明白哪里出了问题
请教大神！

@Cena_2008 请进入你的虚拟机启动的那个虚拟机网络的命名空间里，然后去ping dhcp的地址，看通不通

nova-network的单IP模式，没有用namespace
