Enable Intel-VT on a Mac Pro

[m_30]

How do I enable VT on a Mac Pro, which has an EFI (Extensible Firmware Interface) instead of a BIOS?

I'm running Vista Business 64-bit under boot camp (natively on the processor, not in a VM) on a Mac Pro (Early 2008), which has 2 quad core XEONs E5462, which fully support EM64T and VT. I'm using VMware Workstation 6.0.3 and I've just tried to install Ubuntu 8.04 Hardy Heron 64-bit in a VM, which resulted in the following error message:

"This CPU is VT-capable, but VT is not enabled (check your BIOS/firmware settings)."

I have no clue what to do now. Anyone who had the same problem and has resolved it successfully?

All my 32-bit VMs run fine. But I assume that they would run faster, if VMware Workstation could use Intel-VT. By the way, is there any way of telling, when VMware Workstation is actually using VT?

Hi there,

i know we are like 13 years further now but i have the same issue

On my Mac Pro 1,1 upgraded to a 2,1 running Win10.

Tried to fix by adding "hv.enableIfUnlocked = TRUE" without the " " in de "config.ini" file.

Maybe you can tell me how you got it fixed.

Thank you in advanced.
