Hi Michael ,

Thanks for ur continuous help. I have one more query here ....

I want to fetch the host elements like .. Type address status No. of CPUs cpu->type cpu -> name->topology->cores->sockets memory summary version

Is is the correct way of doing to get these details?

hosts=api.hosts.list() for host in hosts: type=api.hosts.get(host.id <http://host.id>).type address=api.hosts.get(host.id <http://host.id>).address

no, please use getter methods instead as they're encapsulating attributes that may be called differently in python, for instance 'type' attribute in python renamed to 'type_' cause 'type' is preserved name. you can see all available get_X() methods by running code bellow: #> print [token for token in type(host.superclass).__dict__.keys() if token.startswith('get_')]

I got some exception : address=api.hosts.get(host.id <http://host.id>).get_address() AttributeError: 'NoneType' object has no attribute 'get_address'

this can only happen if your host lookup has failed.

Please suggest me the correct way of doing it ....if have referred https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Virtualiza...

this is summary object structure:

<summary> <vms> <total></total> <active></active> </vms> <hosts> <total></total> <active></active> </hosts> <users> <total></total> <active></active> </users> <storage_domains> <total></total> <active></active> </storage_domains> </summary>

you can access properties directly, like this: summary.hosts.active
