I haven’t upgraded my VB in a long time, I’ve heard Sun has made a bunch of changes. Hopefully, they’re improvements.
Vbox is up to 3.02. I’ve been using it since about 2.14 IIRC. I’ve only got 2gb ram in the T61 gave win 760mb and only let it use a single processor. Mapped a drive to the physical vista part no problem.
Performance with the above params is pretty good. You ought to upgrade your VBox they have
made a lot of improvents and it handles win 7 beta pretty good.
