Its pretty hard for me to parse the above or help more without a live
pdb shell looking at this but I wonder if this is a Liberty vs Mitaka
difference? We're still on nova liberty. The nova team may know more
and/or I can figure out more once we upgrade since we may hit this same
issue. One difference is that I'm not using the metadefs stuff but I
don't know if that is relevant or not.

Hello Matt,
I found you blog post to this and tried your code, but the problem
is, that I get an error:

It seems the the call “image_props = spec_obj.get('request_spec',
{})” provides an empty object.
If I write an str(spec_obj.image.__dict__) I get:

So there seems no request_spec present. There's an attribute "image"
within spec_obj that has an attribute properties of the type
ImageMetaProps that has all the vmware related properties that are
defined the same way then our properties, but not our self defined
property.

Betreff: Re: [Openstack-operators] Properties missing in Nova
Scheduler Filter
Mario,
If I remember right I had a similar issue with getting image_props
when I was doing this to pull in custom properties. Through some
trial and error and poking around with pdb I ended up with this:
image_props = spec_obj.get('request_spec', {}).\
get('image', {}).get('properties', {})
Perhaps that will help? If not I'd recommend putting a pdb break at
the top of host_passes and digging through the spec_obj.

Hello,
we are trying to build our own nova scheduler filter to separate
machines to different compute nodes / host aggregates.
Our setup is based on OpenStack Mitaka and we are using VMware as
hypervisor on 3 different compute nodes.
We have created a /etc/glance/metadefs/CV_AggSelect.json file to
define the new property "os_selectagg"
{
"namespace": "OS::Compute::cv-host-agg",
"display_name": "CV-CUSTOM: Select Host Aggregate",
"description": "Cornelsen CUSTOM: Select Host Aggregate",
"visibility": "public",
"protected": true,
"resource_type_associations": [
{
"name": "OS::Glance::Image"
},
{
"name": "OS::Nova::Aggregate"
}
],
"properties": {
"os_selectagg": {
"title": "selectagg",
"description": "Cornelsen CUSTOM: Select Host
Aggregate",
"type": "string",
"enum": [
"windows",
"linux",
"desktop",
"test1",
"test2"
],
"default" : "test2"
}
},
"objects": []
}
Getting the details from our image and the host aggregate we see
that the property is set correctly:
openstack image show e62da4df-318f-48dc-be26-b634e82ec4a1
+------------------+----------------------------------------------------------------------------------------------------------------------------------+
| Field | Value
|
+------------------+----------------------------------------------------------------------------------------------------------------------------------+
...
| properties | description='', hw_vif_model='VirtualVmxnet3',
hypervisor_type='vmware', os_selectagg='windows', |
| | vmware_adaptertype='lsiLogicsas',
vmware_disktype='preallocated', vmware_ostype='windows9Server64Guest
...
We also see the property in the aggregate:
openstack aggregate show 5
+-------------------+--------------------------------------------------+
| Field |
Value |
+-------------------+--------------------------------------------------+
...
| properties | hypervisor_type='vmware',
os_selectagg='windows' |
..
I have created a new simple filter in
/usr/lib/python2.7/site-packages/nova/scheduler/filters just to see
what properties are set for the current image and the host_state.
The filter is also set in the /etc/nova/nova.conf and is executed,
because I'm getting the logfile that ist created by the filter.
The filter only implements the " def host_passes(self, host_state,
spec_obj)" function.
I'm getting the image properties by " image_props =
spec_obj.image.properties if spec_obj.image else {} ", but the
property "os_selectagg" is missing. All other properties like
hw_vif_model='VirtualVmxnet3' are set.
The property is set in the host_state.aggregates list, but not in
the spec_obj.image.properties. What do we miss?
With best regards,
Mario Keller.
Mit freundlichen Grüßen
