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

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

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