[Bug 1061665] [NEW] Filter scheduler not respecting the force_hosts hint

[Dražen Lučanin]

Public bug reported:

When I'm trying to boot instances on a specific host (sleepy) by
issuing:

    nova boot --image mybucket/image.manifest.xml --flavor m1.tiny
--key_name mykey --hint force_hosts=sleepy test-vm

my VMs always seem to start on a random host instead on the one I
targeted. I'm using Essex and the filter scheduler (my nova.conf
contains
`compute_scheduler_driver=nova.scheduler.filter_scheduler.FilterScheduler`).

My user is admin (I sourced /var/lib/nova/novarc), I also have
--allow_admin_api=true in my nova.conf file. The only mention of filter
in my /var/log/nova-scheduler.log is

> u'filter_properties': {u'scheduler_hints': {u'force_hosts':
u'sleepy'}}.

This file also says u'_context_is_admin': True and u'_context_roles':
[u'admin']

Here is the full request grabbed from the nova-scheduler.log file:

The matter was also discussed in this AskUbuntu question:

use-a-specific-host

I'm running Ubuntu server 12.04 and nova-scheduler version
2012.1-0ubuntu2.
