The problem that I am seeing now is that windows vista is seeing only two processors when I am in fact passing 8 (quad core hyperthreading). The issue seems to be that the 8 virtual CPUs on my single physical CPU appear as 8 distinct processors on windows vista enterprise and that edition is limited to two physical processors (see for instance http://en.wikipedia.org/wiki/Windows_Vista_editions#Comparison_chart). Is there a way in which I can pass the 8 virtual CPUs to the vista image in such a way that they appear as one CPU with 8 cores? Cheers Erik
