Hello , guys There's a problem while separate instance's network and nova-management network. EX. Nova management network : 192.168.1.0/24 eth0 Instance network : 10.0.0.0/12 eth1 bridge to br100 During cloud-setup : Instance try to retrieve metadata from 169.254.169.254. Instances(10.0.0.0/12) request 169.254.169.254 PREROUTING from gateway(nova-network). But If PREROUTING rule is already been set on nova-Compute node, instance request will be redirected on VM host instead of nova-network host. So If your topology is like A diadram from StackOps<http://docs.stackops.org/download/attachments/885051/OpenStack_Multinode_Architecture_3d.png?version=1&modificationDate=1300350521000> , Plz Check iptables rule on *Compute nodes*. -A PREROUTING -d 169.254.169.254/32 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.1.2:8773 And del this rule , your instance will get metadata correctly.... -------------- next part -------------- An HTML attachment was scrubbed...
