Hi, I encounter a problem of HostedResourcePool association provider, which can still return expected result with wrong key value, even wrong key name. wbemcli ain -ac Xen_HostedResourcePool http://root:password@localhost/root/virt:Xen_MemoryPool.InstanceID="... localhost:5988/root/virt:Xen_HostSystem.CreationClassName="Xen_HostSystem",Name="zeit" wbemcli ain -ac Xen_HostedResourcePool http://root:password@localhost/root/virt:Xen_MemoryPool.wrong="wrong... localhost:5988/root/virt:Xen_HostSystem.CreationClassName="Xen_HostSystem",Name="zeit" That is mean, with a non existing instance, e.g. a wrong InstanceID name or value as above, it can return results also. Please can you have a look into this? Thanks! Best, Regards Daisy Guo Lian Yun E-mail: yunguol(a)cn.ibm.com IBM China Development Lab, Shanghai, China TEL: (86)-21-61008057
