What does Eucalyptus use 172.19/16 for?

Asked by nutznboltz

When I install UEC I see that there are netfilter nat rules in place for 172.19/16 but I can't find documentation explaining why. What does Eucalyptus use 172.19/16 for?

172.19/16 is a network shorthand for the network 172.19.0.0

UEC comes with MANAGED-NOVLAN mode setting for Eucalyptus. The default
network for the instances (virtual machines on the node controller) are
in that range. You can change that setting
in /etc/eucalyptus/eucalyptus.local.conf
Note that the file says you should not edit it directly, but to best of
my knowledge there is no other way to change network settings.

In case anyone finds this by searching, this is what really solved my problem:

Torsten Spindler, the way to set variables in /etc/eucalyptus/eucalyptus.local.conf without editing it by hand is to put the varibles in another file and use

euca_conf --import-conf MYFILE

on it.

The manual page for euca_conf(8) currently does not document the --import-conf and --upgrade-conf options. The --help option only mentions one of the two

$ euca_conf --help 2>&1 | egrep 'import|upgrade'
   --import-conf <file> import variables from <file> into //etc/eucalyptus/eucalyptus.local.conf

But you can read the /usr/sbin/euca_conf script to see what is done.
