Open Stack

Now as I know have two reason cause the error

1: flavor, the flavor is small than image. so you can change the flavor

2: rdo bug, if you use mutil node, you would found the compute node vm
would show error. the reason is the compute node can not find the neutron.
solve the problem, you need add one iptables rule in control node
http://openstack.redhat.com/forum/discussion/910/havanna-issues-with-multi-node

iptables -I INPUT -s $COMPUTE_NODE_IP/32 -p tcp --dport 9696 -j ACCEPT
service iptables save
