Grinning slightly "measly 8 gig of ram", recalling the Commodore 64...., my first i386 with math co-processor and 1M of ram... But seriously, If you can't devote 2G per OS (plus the GPU RAM necessary for hardware acceleration) under a virtualization, you will see slowdowns. You can squeeze OS into 512M, but you will swap/page often resulting in slowness. Graphics performance is a BIG issue -- especially for gaming performance. Anything relying on proprietary GPU drivers/hardware acceleration can be frustrating to run from a virtualized OS. Both vmware and vbox have gotten much better in this regard. Both allow tweaking installs/resources for 2D/3D hardware acceleration, but my experience has been hit and miss (not to mention the prospect of dedicating another 1-3G of RAM for the GPU) I'm not a big gamer, so others may need to chime in here. For the normal business desktop apps, 1G per virtualized OS is fine - it will be slower than native, but usable. 2G per virtualized OS and you are fine normal desktop use. 2G + RAM needed for custom 2D/3D hardware access, you should have relatively good gaming (1st person shooters may still suffer a bit) The more the merrier... -- David C.
