Description of problem:

The new "preallocate_images" config directive should be added to nova.conf; currently, it isn't.


Search for the string preallocate in nova.conf (after updating to correct pkgs)

[tuser1@interceptor export(keystone_admin)]$ sudo grep -i preallocate /etc/nova/*
[tuser1@interceptor export(keystone_admin)]$

Version Info, and ensure the fix is in :
#-----------------------#
[tuser1@interceptor export(keystone_admin)]$ rpm -q openstack-nova

    cfg.StrOpt('preallocate_images',
               default='none',
               help='VM image preallocation mode: '
                    '"none" => no storage provisioning is done up front, '
                    '"space" => storage is fully allocated at instance start'),
