A fix to Windows 2008 R2 and Solaris 10 BSOD and Kernel Panic on Intel E5 v2 Series
VMware was fast and release a temporary fix to use Software MMU however this is not beneficial as this increase the CPU and memory requirements on certain applications.
So the server vendors with VMware and Intel must have gone through lots of testing and have release the updated KB2073791. The temporary fix will still applies if your server vendors does not have an updated BIOS upgrade to make some changes to resolve this issues.
If you refer to page 50 in the document stated in the KB2703791, CA135 is the known issue as a release document from Intel. Since a processor cannot be altered, a fixed is provided via the server vendors BIOS.
Interesting with virtualization, although we may plan and design for lots of redundancy, there is still one single point of failure we cannot avoid the main core of the hardware which is the CPU which holds the heart to all the workload. The most important thing that we are unable to plan for a redundancy. Good thing on x86, we are still able to use other type of CPU. Imagine you are not on a x86 platform, such incident can still happens especially if you are in a situation where you do not even have a choice of CPU to choose from.
Glad that now all is now resolved.
