  Okay applied thanks !
I would concur with Chris, I think the current practice in most
of libvirt code when there is a complex routine is to handle
OOM with a goto to an error label. This allows to limit the level
of cascading. This is stylistic, but affects readability, and
hence maintainability :-)
