nova host-list cann't return result in xml form

[Ivan-Zhu]

nova-api should can return result in json form and xml form. but the host-list api can only return result in json form.

It can be reproduced as the following step:

1)curl -i http://localhost:8774/v1.1/4ffc664c198e435e9853f2538fbcd7a7/os-hosts -X GET -H "X-Auth-Project-Id: admin" -H "User-Agent: python-novaclient" -H "Accept: application/json" -H "X-Auth-Token: 0e48e3e8473f4aa18299d5c115bc4f5b"

return the following result:

{"hosts": [{"zone": "nova", "host_name": "host1", "service": "scheduler"}, {"zone": "nova", "host_name": "host1", "service": "compute"}, {"zone": "nova", "host_name": "host1", "service": "cert"}, {"zone": "nova", "host_name": "host1", "service": "network"}, {"zone": "nova", "host_name": "host1", "service": "consoleauth"}]}

but if we change "Accept: application/json" to "Accept: application/xml" and use the commang:

2)curl -i http://localhost:8774/v1.1/4ffc664c198e435e9853f2538fbcd7a7/os-hosts -X GET -H "X-Auth-Project-Id: admin" -H "User-Agent: python-novaclient" -H "Accept: application/xml" -H "X-Auth-Token: 0e48e3e8473f4aa18299d5c115bc4f5b"

it will be return the following result:

<?xml version='1.0' encoding='UTF-8'?>
<hosts><host/></hosts>

I think there is something wrong with @wsgi.serializers(xml=HostIndexTemplate) in the nova-api HostController.
