The error was from cinder, not nova, so this suggests to me that
you're copying an image to a cinder volume, for subsequent
boot-from-volume. The cinder device could be too small... but I
haven't made much use of cinder yet (so don't know where the skeletons
are buried :)).

Two questions:
Whats the output of 'nova flavor-list' and secondly, whats the *exact*
command line you are using to boot your instance?
