Cloud VM CentOS yum upgrade NOTICE.

Message

Summary: We've found that an upgrade from CentOS 6.0 to 6.2 causes a kernel panic after reboot. This is due to the kernel update changing the virtual device names that the VM has when it boots. Our cloud vendor will be releasing a patch for this in the not too distant future however in the mean time we want to advise people to watch for this. We have put a knowledge base article online with some simple instructions that will help you avoid this issue.

To the best of our knowledge this only affects Kernels 2.6.32-220.2.1.el6 and above.
