=Notes=
* the floating IPs situation may not work on non-externally routed IPs. this may be why they set up a 179. "public" network by detafult in the RDO setup. i deleted that network * the external network needs to be "flagged" as external. this cannot be done with the UI, but i am told the juno release has a feature where attribute editing. so that the external attribute can be set to Yes. once that is done, MAYBE the system allows floating IPs in that network even if the IP range is not externally routable* basically understand what it takes to get an image created, seasoned, and how we need to maintain these over long periods. i think the main workhorse is qcow2 tools.* these images are like "snapshots" in some way, but a snapshot is frozen and cannot be tweaked.* long term we want to make images like this for testing, e.g. and amahi 7 image that is bootable and it's plain instal. another example is a fully up to date amahi 7 image, etc.* so they are alive in that these images are frozen in time, but one takes a copy and can then evolve it into a new version of the image.* Refer to [https://raymii.org/s/articles/Fix_inconsistent_Openstack_volumes_and_instances_from_Cinder_and_Nova_via_the_database.html Fix inconsistent OpenStack volumes and instances from Cinder and Nova via the database] for correcting instances in error ('''NOTE:''' Use extreme caution as this could corrupt the database.) <u>ALWAYS</u> back up the database before making any changes!None
=Tips=
* Shutdown/Disconnect
** Stop all instances via SSH
** Detach volumes from instances (this may not be neededin Mitaka)
** Verify all volumes detached and instances stopped
** Perform Update/Reboot
* Once system rebooted:
** Verify cinder_volumes (LVM) is operational** Reattach volumes to instances (this may not be neededin Mitaka)
** Start all needed instances
** Verify all instances are operational
