The original mnaio was built using a lot of bash and was tailored
specifically for ubuntu 14.04. The new mnaio was built using a mix of
bash and ansible and was tailored specifically for ubuntu 16.04. This
patch takes the two code bases and combines the best things from each
method and wraps it up into a single code path all written using ansible
playbooks and basic variables.
While underlying system has changed the bash environment variable syntax
for overrides remains the same. This allows users to continue with what
has become their normal work-flow while leveraging the new structure and
capabilities.
High level overview:
* The general performance of the VMs running within the MNAIO will now
be a lot better. Before the VMs were built within QCOW2 containers,
while this was flexible and portable it was slower. The new
capabilities will use RAW logical volumes and native IO.
* New repo management starts with preseeds and allows the user to pin
to specific repositories without having to worry about flipping them
post build.
* CPU overhead will be a lot less. The old VM system used an
un-reasonable number of processors per VM which directly translated
to sockets. The new system will use cores and a single socket
allowing for generally better VM performance with a lot less
overhead and resource contention on the host.
* Memory consumption has been greatly reduced. Each VM is now
following the memory restrictions we'd find in the gate, as a MAX.
Most of the VMs are using 1 - 2 GiB of RAM which should be more than
enough for our purposes.
Overall the deployment process is simpler and more flexible and will
work on both trusty and xenial out of the box with the hope to bring
centos7 and suse into the fold some time in the future.
