Hi all,

I'm about to test the scheduling across zones functionality in diablo,
but the run instance command does not propagate correctly across the
child zones.

My environment:

3 VM's with diablo installed.

PARENT ZONE: Europe1 [192.168.124.47]
                               |
                               |
       CHILD ZONE: Huddle1 [192.168.124.53]
                               |
                               |
               HOST: Machine1 [192.168.124.44]

The nova-scheduler.log shows that:

1. The zone has been succesfully detected:

2. But the run_instance command is not nested correctly:

2011-10-03 13:16:43,266 DEBUG nova.scheduler.abstract_scheduler [-]
Attempting to build 1 instance(s) from (pid=1118)

/usr/lib/python2.7/dist-packages/nova/scheduler/abstract_scheduler.py:226


3. It seems that after executing the zone-boot command the scheduler
state is not correct:

>>sudo nova-manage service list
Binary           Host                                 Zone

Can anyone please help me ? Any suggestions?

Thank's in advance
