Yes, kernel "358". the "359" was a typo.  And... the kernel panic lines were transcribed for a photo I took of the screen after the failed boot.  On second look I see that the version is 2.6.32-358.0.1.el6.x86_64.

So let's start again.

Kernel panic - Not syncing: Attempted to kill init!
Pid: 1, comm: init not tainted: 2.6.32-358.0.1.el6.x86_64 #1

After yum upgrade --enablerepo=epel on two of five machines, one of which is the host for the three VM's that succeeded and the one that failed, just as the host.

I have a screen shot of that VM's boot failure, but I don't know the proper way to include it in a post.

I've uninstalled that kernel and ran yum upgrade again, it still fails on that kernel, on both the host and the VM.  I suppose the good thing is that it happened on a VM guest that is not critical, so I don't have to experiment with the host that has four important guests running on it.

Any ideas?
