I am having a problem being able to get domain information in an Fedora 8 XEN environment.The code does not receive an error status on the XEN kernel and does not get any information. The same code running on the non XEN kernel works fine. I am running default configuration files. Is this a known issue? Do I need to tweak the configuration files? Is there anything else I need to do get the code to work on the XEN kernel? Please point me in the right direction. If any other information is required to assist in answering my question, please let me know. Thank you in advance for your help.
