Hi,
I have some problems with SYSTEM network configuration in my eucalyptus installation...
Every time I try to start an instance it tells me that there are no available ip addresses, and to use the option --addressing private.
I configured the variables VNET_MODE to static and VNET_BRIDGE to br0 on the NC, I commented out all the other options relative to the other ntw configurations (as VNET_SUBNET, etc...)
I also rebooted completely the system to be sure that the configuration change has been taken, but I got the same problem...
What do you think is the problem?
I tried the MANAGED-NOVLAN mode and it works perfectly (so I guess that the installation and the base system are ok)
Thank you
Luca
Hello Luca,
may I ask why you want to use SYSTEM if MANAGED-NOVLAN works for you? SYSTEM and STATIC are usually used when you don't fully control the environment you are running Eucalyptus in: the MANAGED* mode are the fully featured ones.
Anyway, you don't say which distro are you using. In general, whenever you changed network configuration you need to restart the CC using cleanstop and cleanstart, otherwise the system will get confused. In SYSTEM mode you shouldn't receive any error about public addresses since you are not controlling any.

I was trying all the possibilities, just to see how they work and to be sure to understand how to configure eucalyptus :)
Maybe I'm not restarting correctly the processes.. to make a clean restart I do the following:
- /etc/init.d/eucalyptus-nc restart CLEAN=1 or service eucalyptus-nc restart CLEAN=1
- /etc/init.d/eucalyptus restart CLEAN=1 or service eucalyptus restart CLEAN=1
it is correct?
if I reboot the machine do I obtain a clean restart of all the eucalyptus components?
Another question: the eucalyptus.conf file should be the same on all the nodes? I mean, if I have only one component per node do I have to set properly the settings only for that component (below the #EFFECTS COMPONENTNAME line), including the general settings, or the configurations for all the other eucalyptus components are needed?
thank you
Luca
Hello,
I see. Ubuntu uses upstart so you should use the 'restart' command with CLEAN=1: only the CC needs to be restarted that way and a reboot is not enough to clear the state. You need to set the variable in eucalyptus.conf only for the component running on that machine.
