Public bug reported:
I set "VIRT_DRVER=fake" for my devstack.
And when I try to boot instance with flavor "m1.tiny" nova scheduler says that
I don't have disk space -
"ram:799488 disk:0 io_ops:0 instances:0 does not have 1024 MB usable disk, it
only has 0.0 MB usable disk."
It happens because scheduler calculates free_gb as minimum from
'compute.disk_available_least' and 'compute.free_disk_gb' if least is not None
but fake_virt driver defines 'disk_available_least = 0'.
Maybe this is not a bug about booting instance but maybe a bug about
list of flavors for fake_virt driver. (or friendly message that this
operation can not be proceeded).
