Comment 3 for bug 1741810

> You should set the following parameters in nova configuration file (nova.conf).

Sorry. It is not correct.

But in this case, it may work well by the following operations.

openstack image set --property testimg.os=windows img_windows
openstack image set --property testimg.os=linux img_linux

openstack aggregate set --property testimg.os=windows os_win
openstack aggregate set --property testimg.os=linux os_linux

If it does not work, needs more information.
For example:

* The output of 'openstack image show' command
* The output of 'openstack aggregate show' command
* nova.conf file that nova-scheduler uses
* the log file of nova-scheduler
* nova/scheduler/filters/aggregate_image_properties_isolation.py file
* The value of 'x-openstack-request-id' when creating a server (POST /compute/v2.1/servers)
  (You can get it by 'debug' option. e.g. "openstack --debug server create")
