[Gambas-user] Gambas3 & andLinux on WinXP

[Randall Morgan]

I too use vbox mostly on linux hosts but I also run it on my laptop and one
Windows XP desktop. The Laptop is Windows Vista. The only time I have had
an issue with it running slowly was when I used to much memory. Make sure
you have sufficient memory for both OS's. I've got 3gb and still run vista
as host and ubuntu 10 as guest on vbox. However, it is not as fast as on my
64gb machine using Ubuntu 11 host and WIndows ( XP, Vista, 7) guests. Here
there is no noticeable difference between running these OSs directly on the
hardware.

I'd be looking at memory and memory management first then check out other
possible issues.

If you ask me if it can be done. The answer is YES, it can always be done.
The correct questions however are... What will it cost, and how long will
it take?
