Subject: [Openstack] Can't get fix ip via dhcp and can't accociate Floating	ip using quantum

I use quantum as my nova-network in ubuntu 12.04LTS, there are two problem:
1: it can show fix ip, but in vm, the network interfaces have no ips. Using "dhclient eth0" does not make sense. Using "ifconfig eth0 inet xxx netmask xxx" can work.

2: when I accociate floating ip to a vm , it show error, the nova-network log is below:
