Re: VirtualBox High CPU Usage
Have you tried qemu?
If you are running an x86 guest on an x86 host kqemu is really fast. (kernel mode accelerator)
Slow downs come when you are trying to run a, for example, mips guest on an x86 host.
Because of the translation of commands its a lot slower.
I use Qemu now, virtual box I found to be too slow, vmware is too bulky and proprietry (and very slow).
Also your processor is quite slow and outdated, with a faster processor you will end up with much better performance.
And also having dual cores helps a lot (as you obviously have the guest running mainly on one core and your host mainly on the other)
I currently run XP in a qemu virtual guest on my laptop and my desktop. Its fast enough to use happily on my laptop and its natural speed on my desktop.
