vSphere 5.1 Update1 PSOD Fix Build

VMware released 5.1U1 on April 25th with Build 1065491.  There were some critical bugs identified and fixed, so if you are using 5.1U1 with Intel Processors, you may want to use build 1117900, which came out May 22nd.  This build fixes some bugs about occasional PSOD (purple screen of death) related Flex Priority in Intel processors (part of the VT featureset).
