Running 64-bit guests with VMware Workstation 6.0

by rastix on Mon 12 Feb 2007 09:52 PM CET

I recently got my hands on an HP nw8440 mobile workstation with a dual-core Intel Core 2 Duo processor (T7400 @ 2.16Ghz). Those processors have EM64T and Virtualization Technology (VT) support. Those two technologies make it possible to run 64-bit guests with VMware Workstation. I am running Windows Vista Ultimate so I decided to install VMware Workstation 6 on it.

At first it did not work because, for some unknown reason, HP ships these laptops with VT disabled and without an option in the BIOS to enable it. After downloading and installing the latest BIOS from hp.com, I could enable VT in the BIOS. After enabling VT, you have to power down the system and start it again for VT to become active.

With VT active, VMware Workstation 6 was able to run a 64-bit guest without issues as expected. See the screenshot with Windows XP x64 running as a guest on Vista as a host (click to enlarge).
