I traversed all of the documents and Q/A wesites but I could't find
the solution. My nova is down because of an unexpected error logged at
nova-api.log file(see the message thread).
How can I solve this problem?
Thanks in advance...

I fixed it. But now in my nova-compute.log a new error meesage was shown:
unexpected error while running command. command: sudo nova-rootwrap
/etc/nova/rootwrap.conf iptables-restore -c
exit code: 2
stdout: ''
stderr: "iptables-restore v1.4.21: iptables-restore: unable to
initialize table 'nat'

How can I fix it?
My iptable_filter kernel module is also loaded.
