[CentOS] A bit perturbing

I'm doing an update on a machine that does have VMs running on it, and I
see a number of complaints to the effect of
WARNING:
/lib/modules/2.6.18-194.32.1.el5/weak-updates/kmod-kvm/kvm-intel.ko needs
unknown symbol kvm_vcpu_init
WARNING:
/lib/modules/2.6.18-194.32.1.el5/weak-updates/kmod-kvm/kvm-intel.ko needs
unknown symbol kvm_mmu_invlpg

And there are a lot of them (more than I can scroll back to. Has anyone
else seen this?
