I'm planning on buying a ThinkPad T410i with an Intel Core i3-330m CPU at 2.13GHz. After reading Intel's quick spec sheet on this CPU (http://ark.intel.com/Product.aspx?id=47663), I see that it supports Intel VT-x, but it does not support VT-d.
I am planning on running a 64-bit Linux as my main OS, but I would like to have a Windows 7 x64 guest running in VMware Workstation. Will this be possible without VT-d? If so, what, if anything, will I lose without VT-d? Will I be able to run Aero in the virtual machine without VT-d?
VT-d is only required for pass-through physical devices, which Workstation doesn't support. As long as you have VT-x, you're fine.
