Razique, thanks for the tip.<br>To find out which tables has the hostname set I did this:<br># for i in `mysql -uroot -p'PASSWORD' -e 'show tables;' nova | grep -v -e '+' -e 'T'`; do echo $i && mysql -uroot -p'PASSWORD' -e "select * from $i";' nova | grep OLD_HOSTNAME; done<br>
This will print many data with the name of the tables and after all occurrences of the HOSTNAME inside the tables.<br><br>Then I've changed all host to the correct hostname<br><br># for i in {187..190} 193 195; do mysql -uroot -p'PASSWORD' -e "update TABLE set host=NEW_HOSTNAME where id =$i;" nova; done<br>
<br>i.e: # for i in {187..190} 193 195; do mysql -uroot -p'PASSWORD' -e "update floating_ips set host='oxala' where id =$i;" nova; done<br><br>Thanks man! it solved my a part of my issue.<div class="HOEnZb">

Update these fields too and you should be ok :)</div>

My setup is 1 cloudcontroller + node and 2 node with FlatDHCP, mult_host, net HA.<br><br>Recently I've changed the hostname of my cloudcontroller; to make things consistent I've updated the services table inside nova db to mark as deleted=1 the lines where host=oldhostname.<br>
<br>I dont know what happened because now nothing of the nova-network works. It doesn't create br100 anymore, neither iptables rules of SNAT and DNAT<br><br>The worse thing about that problem, is that this is production setup. All my instances from the cloudcontroller are unavaible cause of this. Nodes are creating everything regularly<br>
<br>I couldn't found nothing wrong on logs, no errors. Anyway, here are my logs and setup files.<br><br>controller nova.conf: <a href="http://paste.openstack.org/show/28095/" target="_blank">http://paste.openstack.org/show/28095/</a><br>
