Enable Hardware virtualization in VMware Workstation 8

During installation process of vSphere ESXi 5 as a virtual machine I got warning message

HARDWARE_VIRTUALIZATION WARNING: Hardware Virtualization is not a feature of the CPU, or is not enabled in the BIOS

I talked to myself, what the hack, I did enabled INTEL-VT in the BIOS. I skipped warning message and finished installation.

Without enabled hardware virtualization feature I would be able run only 32 bit machines on my virtual ESXi server. I decided to dig out in virtual machine configuration.  In a hardware tab, under Processor configuration section Virtual Intel-VT or AMD-V/RVI box need to be checked in order to pass hardware virtualization features to virtual machine

    Hey dude, that was a big lie!! That box remain checked and still complaining of same man!

    • do you have Intel-VT enabled in BIOS ?

      • Joseph Ozurumba

        Yes I did before coming online to search for the information, sorry for my harsh words though, was very sad after immediate turn-down.

        • as you can from the comments below, it does work for others – to sure why it doesn’t for you. One of the comments mention something about Trusted Execution to be switched off.Check it – maybe it will help you out
