I have a development server, an HP DL380 G5 that I have installed ESXi 5.0 with a few virtual machines.  (I understand this old of a server cannot use newer ESXi versions).
After getting everything set up I looked into vSphere\Configuration\Processors and realized hyperthreading was not engaged.
so I booted into BIOS and enabled "Intel (R) Virtualization Techology", however it still is not showing on ESXi.  See below:
ESXi Config-Processors.
Is it to late to enable after the ESXi install?
Server has 2 Xeon Dual Core 3.0GHz processors. only giving me 4 Logical processors.

Server does not support hyperthreading or not enabled in BIOS.

Your server is not on the HCL, but this does not mean, it does not work, it's just it's not supported.

Thanks Andrew,
I have enabled it, but if it is not supported then maybe I will use it for a physical server and find another for ESXi.
Have a great day,
