The goal of stateless, and thus this change, is to separate OS configuration
from system administrator configuration. With this change we will read the
default configuration data from /usr/share/defaults/qemu, in the absence of
an overriding site administrator configuration in /etc/qemu.
A key advantage of this change is enabling a sane and immutable default OS
configuration, that is resiliant to upgrades. Ultimate power is still left
to the system administrator, with the ability to override the defaults if
required. Lastly, given that the sane defaults are always available, the
administrator may simply remove their site-config files to reset the
configuration to the "factory defaults" (i.e. OS configuration).
