AFAIK, you can use up to the number of real cores. HOWEVER, using more than one core will cause problems, why? never had one with ACPI my production servers use 1, 2 or 4 cores, i never had one hang or trap >and it will likely not make much difference in performance (it makes very little difference when running a XP, or win 7, guests). no, sorry, they do if you are using real world production servers >>From what I see, VBox uses support similar to Hyper Threading, and Hyper Threading is not very friendly to OS/2. > > Try it, and see what happens. I suspect that it will hang after a short period. I haven't tried it for a couple of years, something may have changed (but I doubt it). my production servers use 1, 2 or 4 cores, i never had a trap or hang or whatever my only doubt was MP (3,5,7) not SMP number of cores you didn't try that ok, thanks anyway massimo
