[libvirt] possible bug regarding cpu flag 'pclmulqdq' in cpu_map.xml

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, laine on IRC was so kind to redirect me to this list, so I didn't file a BZ at: https://bugzilla.redhat.com/enter_bug.cgi?product=Virtualization%20Tools &component=libvirt yet. Please keep me CC'ed as I'm not subscribed to the list. So here is my bug report: Description of problem: I believe the flag "pclmulqdq" is wrongly spelled in cpu_map.xml leading to wrong cpu being detected: Version-Release number of selected component (if applicable): current master: https://libvirt.org/git/?p=libvirt.git;a=blob;f=src/cpu/cpu_map.xml;h=21 10c0b9b2a2a70f0334b2ff63416bd1b704b669;hb=HEAD How reproducible: always Steps to Reproduce: 1.install e.g. ovirt, or some other libvirt consumer on a system with a cpu like intel xeon E3-1230 2. it will get reported as nehalem 3. Actual results: cpu gets reported as "nehalem" Expected results: cpu gets reported as "sandy bridge" Additional info: I found no real info on this flag: grep --color pclmuldq /usr/share/libvirt/cpu_map.xml <feature name='pclmuldq'> <feature name='pclmuldq'/> <feature name='pclmuldq'/> wikipedia (not always right, I know) and Intel just seem to know the flag 'pclmulqdq' See: https://en.wikipedia.org/wiki/CLMUL_instruction_set https://en.wikipedia.org/wiki/CPUID#EAX.3D1:_Processor_Info_and_Feature_ Bits https://software.intel.com/file/36945 But the Intel documentation is vast and I might have missed information on their website. So please check if this is the correct cpu flag indeed. Thanks! PS: If this is a real bug, it goes way back into el6 released versions of libvirt, and I would like to see a backport, if possible! Here is the BZ which introduced the flag: https://bugzilla.redhat.com/show_bug.cgi?id=761005 I guess this got wrongly typed, when you look at this comment, which has the correct notation: https://bugzilla.redhat.com/show_bug.cgi?id=761005#c16 - -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
