Is this something I should be concerned about or can it be disregarded without consequence?
Possibly in some installs this is indeed something to worry about. The weak-updates will only work on kernels that meet all the requirements in the kmod.
This means that "kernel >= 2.6.18-203.el5" ... if you have any kernels older than that on your box, when the weak-updates run, it will fail and there are missing symbols. If you have a mix of kernels above and below the 2.6.18-203.el5, you will get this error on the older ones.
As long as you only boot kernels that are >= 2.6.18-203.el5, then it should not be a problem.

Oh, and I would point out that if you did not have at least one kernel installed that is above the 2.6.18-203.el5 version, then the package would not install at all, so in this case you likely have a mix of older and newer kernels on the box.

We keep the last three kernels installed as a matter of policy and the oldest of these on the development box is kernel-2.6.18-194.32.1.el5. I do not plan on booting into an older kernel on this host. Therefore, I will work from the assumption that this issue is not going to cause us any difficulty and will disappear on its own with the next kernel update.
Thank you.

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.
