According to the VirtualBox manual: http://www.virtualbox.org/manual/ch03.html#intro-64bitguests The CPU needs to support hardware-assisted virtualization in order for VirtualBox to support 64-bit guests. Without the CPU support, VirtualBox cannot do it. I double checked this with CoreInfo.exe from Windows Sysinternals utilities, and also from the Intel data sheet for my CPU: http://ark.intel.com/products/30787 (VT-x option not supported) I will use QEMU under Windows until I can get a better machine. :) -- Craig Rodrigues rodrigc@crodrigues.org -- Craig Rodrigues rodrigc@crodrigues.orghelp
