For class providers sfcb is
acting like Pegasus. It translates the
CIM_RASD call into a separate provider request for each subclass.

Hmm.. interesting. No, this was with Pegasus. Here's error - I don't
see anything strange in the CU_DEBUG output.
[kaitlin@elm3b41 libvirt-cim]$ wbemcli ein
http://localhost/root/virt:CIM_ResourceAllocationSettingData
*
* wbemcli: Cim: (1) CIM_ERR_FAILED: A general error occurred that is
not covered by a more specific error code: "Unable to get domain list"
I see the following with ei:
[kaitlin@elm3b41 libvirt-cim]$ wbemcli ei
http://localhost/root/virt:CIM_ResourceAllocationSettingData
*
* wbemcli: Cim: (2) CIM_ERR_ACCESS_DENIED: Access to a CIM resource
was not available to the client: "Recursive Use of CIMOMHandle Attempted"
Besides that tiny compilation issue I had no trouble with the provider -
neither with sfcb nor with Pegasus. And by reviewing the code I have no
idea, where this behavior could come from. For me everything looks fine.
What is really strange is, that for nearly the same call two different
functions are returning errors:
- for the first one (ein) the provider is returning the error
- for the second one (ei) the CIMOM is returning the error ... and that
error looks like Pegasus is having trouble with calling the same
provider for different subclasses
Please can you reinstall, restart Pegasus and try again ? What happens ?
