Right - if there is a case for making nova disallow boot from image (that is stored on a local drive) than max_local_block_devices is little crude as setting it to 0, as it will disallow swap drives too.
Looking at the code - setting root_gb to 0 in the flavor seems like it would do what you want actually - have you tried that?
