Does Boot Camp disable Intel-VT?
Here is the background to my question: I have a Mac Pro (Early 2008) with 2 quad core XEONs E5462, which are obviously capable of VT (Intel's virtualization extension for x86 architecture). I say "obviously", because I can run Ubuntu 64-bit without problems in a VM (virtual machine) in VMware Fusion under Mac OS X 10.5.2.
But I'm unable to get the very same VM running in VMware Workstation 6.0.3 under Vista 64-bit. Therefore I'm a bit confused (and annoyed) how to get VT running under boot camp. In most forums they'd give you the advise to turn on VT in the Bios. But we all know about EFI... Anyway the problem might not be EFI, because VT is supported under Mac OS X.
From a tech guy in the VMware forum I got the following description:
With VMware Workstation 6.0.3, you should be able to check the vmware.log file for the monitor extensions that are loaded. If you see hv-vt.vmm32, then the 32-bit monitor is using Intel VT. If you see hv-svm.vmm32, then the 32-bit monitor is using AMD-V. If you see hv-none.vmm32, then the 32-bit monitor is using binary translation. Substitute 'vmm64' for 'vmm32' and you get the answer for the 64-bit monitor.
All the log-files of my 32-bit VMs running in VMware Workstation show "hv-none.vmm32", so there is no VT active under bootcamp (neither running Windows XP 32-bit nor Vista 64-bit).
So, if boot camp actually does disable the Intel-VT, is there a way of enabling it again?
