Hello,

to clarify, the nova-scheduler is just saying that the boot process
can't succeed because none of your registered computes fit, or there is
none at all (from scheduler pov).

First thing first:

- flavor specs ?
- do the computes register correctly their resources ? (check that in
nova-compute logs)
- are you using aggregates ?
- you should enable the debug/verbose mode on the controller and read
the nova-scheduler log in detail

Regards.
