- Second Node : nova-compute<br><br>I'm using diablo version that was installed from the ubuntu repository, which i suppose is the nova 2011.3+git20111117-0ubuntu1 oneiric version.<br><br>For what a read, the second node only needs nova-compute ,but sometimes i see others saying about using nova-network together. I'm using machines that have just one network interface, so they are in the same network with other non-OpenStack computers (this network uses dhcp).<br>
At the network configuration i'm using flatDHCP. The nova.conf file can be see here (the ip is not exactly what im using, is just a template): <a href="http://paste.openstack.org/show/3978/">http://paste.openstack.org/show/3978/</a><br>
<br>So, i'm able to install and run virtual machines in both nodes. My problem is, for any instance that is running on the second node, i can't connect with the outside world (i can ssh and ping it from the first node, but not from an outside computer). Into the first node all goes fine.<br>
<br>If i restart nova-network (not exactly one time, sometimes more) at some point nova-network goes down, and then i'm able to ping the instances. Is like the configuration is good but the service break. The error that appears on logs is Stderr: 'RTNETLINK answers: File exists\n' - <a href="http://pastebin.com/qYhhYS6h">http://pastebin.com/qYhhYS6h</a><br>
<br>Currently i'm trying the same configuration in another 2 computers, using the diablo-final version of the rcb repository, as the openstack forum suggest. The errors is different. From what i remember (i'm not the only working with that) i was not even able to ping instances from outside after restarting the nova-network. <br>
Then we tried to use nova-network with the second node too. After some time, new instances running on the second node start gracefully, and i can ping them from outside, however i can't run instances on the first node anymore. There's no log errors at nova or qemu folder, i can vnc to the instance but it appears stopped (cant do nothing).<br>
<br>I appreciate any help<br><br>
