For curiosity sake, does anyone know why this option is disabled in the BIOS from the factory?
I have a client asking as to why we do not enable this feature when deploying and I don't have a good explanation.
Solved! Go to Solution.

Its mainly a feature that might be required if you plan on running hardware virtualization need by sertail virtualization software. En Example is virtualbox.
Again, its a feature, not something that is needed by all.

Thank you for the quick response, but the explanation didn't exactly answer the question.
I understand what the feature is and what it is used for.
I guess a better question to ask, "Is the Intel VT feature disabled by default from the factory due to security concerns, adverse performance issues fordeployments not utilizing local vituralized environments, or an alternate reason?"

Here is the answer I believe you were looking for...
"Hardware Virtualization is technically a bit of a security hole. While most problems have been fixed there were some rootkits which took advantage of the functionality to get higher running privileges than the OS itself. Basically, it could execute code directly on the CPU (bad).
That being said, it's not really a problem anymore. I don't think I've ever used a laptop/desktop/server which has had it enabled by default. So this isn't just limited to HP. But I'm guessing the general consensus is if someone needs it to be enabled, they have the brains and understanding to do it themselves."
