I have a Windows 7 64 bit with lots of RAM hosting a VirtualBox VM with a Windows XP guest. The apps run on the guest use so much ram that it typically ends up swapping.
I'd like to know any tips for configuring the guest or host so that the guest gets best use of the hosts RAM as a disk cache (particularly for the swap file?)
In particular, is there any way to get the Win 7 host to use most of its RAM as a disk cache (or will it do that anyway)?
Should I change any settings in the XP guest to run well in this environment?
