Hi, I try to test VirtualSystemManagementCapabilities and get results as follows: "wbemcli ein http://root:password@localhost:5988/root/virt:Xen_ResourcePoolConfigurati... localhost:5988/root/virt:Xen_ResourcePoolConfigurationCapabilities.InstanceID="" As a property of ResourcePoolConfigurationCapabilities, is InstanceID need to set in provider?
