It seems work fine for creating a guest, i.e. I can set the cpuset by
"virsh create" with XML file containing a cpuset parameter.
This fix will solve "create" of the following BZ. 
  - BZ#223833: 
    FEAT RHEL5.2: About the setting of CPU affinity at virsh create/reboot

I think we also need to fix for "start/define/dumpxml".
So, I attached the patch for them. Could you check it ?

Anyway, I will have some more test for the cpuset.
