回复： {Disarmed} Re: VMs are not getting IPs
Why not create the bridge automatically as nova-network did?
I am not sure what the concern is.
Regards,

主题: Re: [Openstack] {Disarmed} Re: VMs are not getting IPs
If you're running quantum-dhcp-agent, or quantum-l3-agent on a node, you also need to be running the plugin agent. For example, see the page in the quantum install guide about installing the dhcp agent: http://docs.openstack.org/trunk/openstack-network/admin/content/install_quantum_dhcp.html
We can't make sure that all tutorials out there are up to date, so please use the Quantum Admin Guide to supplement any tutorial.
