Public bug reported:

When you unshelve an instance, the instance will be created on a Compute-Node that belongs to an aggregate which  
doesn't have same metadata.

conditions:
　・An cinder volume is attached as a bootable volume.

　・AggregateImagePropertiesIsolation filter is in scheduler_default_filters of /etc/nova/nova.conf file.
　
  ・Propertes are defined in an image's metadata
     For example　key:'CentOS' value:'true'        

  ・two or more aggregates exist.one of which has same metadata as image's Property.　
　・an instance on host that belongs to the aggregate which has same metadata.

 Reproduce steps:
  1.shelve an instance
    # nova shelve UUID

  2.unshlve an instance
    # nova unshelve UUID

Expected result:
 the instance is on a Compute-Node that belongs to an aggregate which has same metadata.

Actual result:
 the instance is on a Compute-Node that belongs to an aggregate which  doesn't have same metadata.

environments:
 Icehouse
