Hi Laurent,

It seems to be a sandy bridge processor ? I did a quick seach on the 
error messages, and found two RHEL bug reports stating that these were 
only warnings with KVM that were harmless (not a bug). See :
https://bugzilla.redhat.com/show_bug.cgi?id=609032
https://bugzilla.redhat.com/show_bug.cgi?id=507085

So, no worry

Alain
