my guess is you have the old 2.6.18-194.32.1.el5 kernel installed, 
hopefully in addition to the newer 2.6.18-238.* versions.
"rpm -q kernel" will tell.
the new kmod-kvm may not work with the older kernel. Just uninstall it 
(the old kernel) if you don't need it, and you won't get those warnings. 
kmod-kvm probably won't work with the old kernel anyways.
Of course you should install and use the newer kernel.
