After verifying the download and dd'ing it onto a USB drive, I was unable to boot Qubes on my Thinkpad T60 (Intel GMA 950 GPU, Intel Core 2 Duo T7600 processor). I got a series of lines that said "unkown keyword in configuration file:" each followed by a different series of symbols, numbers, and letters and then a final termination with an error that said "No DEFAULT or UI configuration directive found!"
Considering my processor does not support Intel VT-d, is it even worth running Qubes on my machine? I.e., does the absence of VT-d ruin network isolation or reduce it?
