Install OpenStack following RDO Quickstart instructions (run packstack --allinone as root)
Configure network bridging (refer to RDO Reference)
- Set CONFIG_PROVISION_ALL_IN_ONE_OVS_BRIDGE=n in packstack-answers-20141028-205455.txt
- Executed packstack --answer-file=packstack-answers-20141028-205455.txt (as root)
- Created /etc/sysconfig/network-scripts/ifcfg-br-ex
- Revised /etc/sysconfig/network-scripts/ifcfg-enp9s0f0
- Appended lines to /etc/neutron/plugin.ini
- Restarted the network service
- Removed router and subnet (ALL instances must be terminated to remove subnet)
- Recreated subnet with IP address allocation range (set floating IP addresses)
- Recreated router to match gateway
Configure DNS to access internet
- Edit /etc/neutron/dhcp_agent.ini and uncomment the line below:

# Comma-separated list of DNS servers which will be used by dnsmasq
# as forwarders.
# dnsmasq_dns_servers =

and add 8.8.8.8,8.8.4.4 after equal (=), then reboot as I could not determine what services to restart.

This will outline how to build OpenStack images using Proxmox VE.

Log into Proxmox VE web UI
Create a VM or clone an existing one
1. If creating a VM, install the OS
2. If using a clone, start the VM
Open a console window for the VM
1. Log in and as root do the following
  - dd if=/dev/zero of=/mytempfile bs=1M (zero out any unused space)
  - rm -f /mytempfile
2. Shutdown VM
3. Log into Proxmox VE via SSH and execute the following from command line
  - Navigate to /var/lib/vz/### (number of VM)
  - mv original_image.qcow2 original_image.qcow2_backup (rename original image)
  - qemu-img convert -O qcow2 original_image.qcow2_backup original_image.qcow2
  - Copy new .qcow2 image to a safe location for uploading into OpenStack
  - Remove .backup file
  - Delete the VM from Proxmox VE web UI
Use WINScp or similar program to copy the .qcow2 image to client machine
Upload into OpenStack via the web UI

REF: Reclaim disk space from .qcow2 or .vmdk image

Coming soon...

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.

When a volume becomes detached and/or shows in error, the state can be reset.
