try:

                        compute.login,
                        compute.password,
                        compute.type)
     get_instances = conn.get_instances()
 except libvirtError as err:
    errors.append(err)

for instance in get_instances:
    try:
        inst = Instance.objects.get(compute_id=host_id, name=instance)
        uuid = inst.uuid
    except Instance.DoesNotExist:
        uuid = conn.get_uuid(instance)
        inst = Instance(compute_id=host_id, name=instance, uuid=uuid)
        inst.save()
    instances.append({'name': instance,
                      'status': conn.get_instance_status(instance),
                      'uuid': uuid,
                      'memory': conn.get_instance_memory(instance),
                      'vcpu': conn.get_instance_vcpu(instance),
                      'has_managed_save_image': conn.get_instance_managed_save_image(instance)})

@retspen .... Can you explain it for me ??? Please !!! :((

@marukochanstella hi, it gets list of vm domains from libvirt with specified hostname. Then it gets list of vm domains from internal database for specified host. then it check if there is any new domains. if there is a new domain it adds to database. after that it gets info of domain to show.

sum:

get instance list from libvirt
add them to database if it is not already in database
add instances info's to a list to show.
