During the webcast which I did for the SQL PASS Virtulization Virtual Chapter on July 13th, 2011 a question came up that I didn’t have the answer for. The question was if I had done “Any testing on the effect of Hiding NX/XD flag from guest with SQL Server on ESX?”. I hadn’t done any testing of this, so I kicked the question over to a friend of mine in the VMware world Gabrie van Zanten (blog | @gabvirtualworld) who hasn’t done any testing of performance effects of hiding this value. Gabrie told me that he hasn’t heard of any performance problems with this setting that would change the general use of this setting for a SQL Server specifically.
