[Bug 1265877] [NEW] nova fails to launch i386 images

[LaMont Jones]

Public bug reported:

in nova.conf:
compute_scheduler_driver=nova.scheduler.filter_scheduler.FilterScheduler
scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,DiskFilter,CoreFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter

The openstack deployment has several compute nodes, all of them running
64-bit installs.  The above config results in:

vm_type:all does not support requested instance_properties host_passes
/usr/lib/python2.7/dist-
packages/nova/scheduler/filters/image_props_filter.py:83

And error-state for all attempts to launch a 32-bit image.

The same applies with:
compute_scheduler_driver=nova.scheduler.chance.ChanceScheduler

Dropping ImagePropertiesFilter from the filters list "fixes" the issue,
but clearly there is no reason that the 64-bit box cannot run a 32-bit
image in a vm.
