hi, I had been fighting this problem for days, and right now knew it perhaps was a bug, got it from : https://bugs.launchpad.net/ubuntu/+source/nova/+bug/907197
It was happened in a fresh install for compute node base on ubuntu newest version 12.04LTS, including nova-compute,nova-network,nova-api. Both of nova-compute and nova-network could start normally and I also could get smile face in NovaCC node. But when i created a new instance and was sent to that new node by scheduler , it always could not get success and always show: Stderr: "iptables-restore v1.4.12: host/network `None' not found\nError occurred at line: 23\nTry `iptables-restore -h' or 'iptables-restore --help' for more information.\n". I am not sure it is same as the bug report and i appreciate if someone could give me a help how to fix this problem, it stopped me for days to run a new node. Best regards, Romi
