Comment 2 for bug 460089

Network state refers to instance IP addresses and active security group rules (user defined instance network ingress policies). It is important to be able to maintain this state in the following scenario:

Eucalyptus is up and running
Users are running VMs and logging in/accessing them via the network
The machine on which the CC is running fails or reboots

Currently, if this happens, all currently running VMs will lose network connectivity when the CC state is cleared. If the files in '/var/lib/eucalyptus/CC' are not removed, then the CC will restore the system's network state when the machine comes back and the CC is restarted. Otherwise, all instances will need to be terminated and restarted.

This issue arises when Eucalyptus is in MANAGED, MANAGED-NOVLAN, and STATIC networking modes.
