Code Issues Proposed changes

Nano and Micro flavors should run really small cirros only

Browse Source 
Guests with large memory requirements can use default flavors, so
removing the special flavor for ppc64 since new qemu requires more
memory - http://wiki.qemu.org/ChangeLog/2.4 - PowerPC.
Users should set DEFAULT_INSTANCE_TYPE to one of the default
flavors available in local.conf, as m1.tiny.

Instance Type
-------------
``DEFAULT_INSTANCE_TYPE`` can be used to configure the default instance
type. When this parameter is not specified, Devstack creates additional
micro & nano flavors for really small instances to run Tempest tests.
For guests with larger memory requirements, ``DEFAULT_INSTANCE_TYPE``
should be specified in the configuration file so Tempest selects the
default flavors instead.
KVM on Power with QEMU 2.4 requires 512 MB to load the firmware -
`QEMU 2.4 - PowerPC <http://wiki.qemu.org/ChangeLog/2.4>`__ so users
running instances on ppc64/ppc64le can choose one of the default
created flavors as follows:
