I was wondering if there is any interest in adding an "on_shared_storage"
field to the Instance class. This would be set once at instance creation
time and we would then be able to avoid having the admin manually pass it
in for the various API calls (evacuate/rebuild_instance/migration/etc.)
It could even be set automatically for the case of booting off block
storage, and maybe we add a config flag indicating that a given compute
node is using shared storage for its instances.
This would also allow for "nova host-evacuate" to work properly if some of
the instances are on unshared storage and some are booting from block
storage (which is shared). As it stands, the host-evacuate command assumes
that they're all the same.
Thoughts?

*What* is on shared storage?
The boot drive?
A snapshot of the running VM?
