I absolutely agree. Such a function should become part of libcmpiutil.

Yep, as far as I can tell, almost everything in the tree right now returns CMPI_RC_ERR_FAILED as a generic failure code. We'll have to spend some time going back to tweak all of those at some point. However, since you've identified this one, I'll tweak and re-send my patch. -- Dan Smith IBM Linux Technology Center Open Hypervisor Team email: danms@us.ibm.com
