Open Stack

Hey Abel,

When I say 'wiped everything clean" I mean that we made backups of the
databases and configuration on all hosts before reinstalling Ubuntu 14.04
LTS on top to start with a clean slate, we did this because we decided to
make the change to the LinuxBridge agent from the OpenVSwitch agent plus we
where upgrading from Icehouse to Liberty, this along with a major
restructure with how our network is laid out.

Really I'm just looking for some input on if I should attempt to extract
the records of the instance backed up from the database and manually insert
them or if I should take the instance dicks and load them in as images and
spin them backup from there.

Hopefully I made a bit more sense this time, sorry.
