Comment 1 for bug 1245541

It looks like that any key in instance_type_extra_specs field is not recognized by the compute_capabilities_filter at all.

For testing, I've added the following code into libvirt.HostState.update_status() function:

        data['pci_passthrough_devices'] = \
            self.driver.get_pci_passthrough_devices()

+ data["test_key"] = 'test_value'

Scheduler cannot find the value of the key from the state of compute node.

 Should the new key:value pair be inserted somewhere else?
