While last time I tried to run a 32bit guest, it took me a lot of time to setup. If my understanding is correct, to run on a 32bit machine, we not only need the kernel but a whole 32bit system. This means I need to re-install a 32bit system. And I found many distro doesn't support 32bit system any more. Do you have a better way to setup the environment? >-- >With Best Regards, >Andy Shevchenko -- Wei Yang Help you, Help me
