Hi all,

is it possible to give 3 or 5 cores to an AOS503 guest VM?



Yes.  AFAIK, you can use up to the number of real cores. HOWEVER, using more than one core will cause problems,

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
